I've known about geocaching for a long time, but until recently, I'd never actually done it. Basically, geocaching is where you hide a small box with little things in it and post its coordinates on the Internet so people can try to find it. People who find your cache can sign a log in the box and swap out whatever little trinkets you have in there. It's for people who like treasure hunting and going out into the wilderness and things like that.

My suitemates Adam and Cameron recently found out about geocaching, and one of the first things we did together when we got back from winter break on Sunday was to look for some caches in the woods next to our dorm. Cameron had seen on the geocaching web site that there were two there. With their coordinates programmed into his GPS, we set out to find them. Adam found the first one in a tree that had fallen over. That one was pretty easy. Searching for the next one was pretty interesting because it took us to an area we didn't even know existed; it was pretty scenic, like a park.

The spot where the cache was supposed to be was near a boardwalk, so we looked over and around it and in the surrounding woods, but to no avail. Finally, Cameron found a hidden container with a few things in it -- but it wasn't a geocache. It was a letterbox; letterboxing is similar to geocaching, but this wasn't the cache that Cameron had found out about online. The notebook inside indicated that it had been placed earlier that same day.

So the search continued. Eventually, I found a box that was hidden along the side of the boardwalk; it was the same color as the wood, so it was camouflaged very well. That was the geocache we were looking for. According to the log inside, numerous people had found it over the past few years.

It only goes to show how popular geocaching and letterboxing are. Maybe I should get into it. I do have a GPS receiver at home that I never found much use for. And if we were able to find two (actually three) caches in such a small area, I can't even imagine how many there must be all over town. (Actually, if I went to the geocaching web site, I could look it up, and then I would be able to imagine it.) And, of course, it would be cool if I hid my own cache somewhere and checked back to see if people had found it. It's a cool idea.

Buying textbooks is kind of crazy. Luckily, my purchases were covered under my financial aid, but that doesn't mean that things had to go smoothly. As I picked up my order from the bookstore on Monday, they gave me the wrong Physics books; I was supposed to get parts 1 and 2 of the textbook when instead I got parts 3 and 4. Unfortunately, I didn't notice till I had gotten back to my dorm, so going back and trying to explain the situation was a big hassle. I got the books I needed, and to give back the ones I didn't, I was redirected to the return and exchange line, which started outside the door of the store. My new books set off the anti-theft alarm. Lovely, right?

So I'm trying to explain to the security guard why it seems like I'm stealing these books. I don't think he really suspected that, but when you have a store security guard saying "Let me get this straight..." to a long-haired college kid in a Rolling Stones t-shirt, it tends to look suspicious. Once I managed to explain that I paid for parts 1 and 2 and needed to return parts 3 and 4, they held the new books for me (standard procedure, y'understand) while I waited in line to give back the books I didn't need. Finally, when I got the cashier there to understand what was going on, he deactivated the bar code on my new books, which a staff member had brought over, and took back the books I got by mistake.

I should have kept them for next year.

I haven't had much luck selling my books. I managed to unload my chemistry book, but my calculus book is now out of date, and nobody wants the old edition. I did sell my course pack for Social Geography, though; I pulled it off by standing outside the class as it got out on Tuesday and asking if people wanted to buy it. I was asking $50, but the guy I was talking to only had $45, so I took that. Not bad for a $63 book.

New feature: when comment on a post, you can now choose to be notified of future comments on the post via e-mail. I've tested it out, and it seems to work, so give it a try. With each e-mail, you'll be provided a link to manage your subscriptions and even change your subscription e-mail address. As usual, your address is safe with me; it won't be given to anyone ever in any way. I enjoy this feature when it's employed on other blogs (such as mcgees.org and now All About Me - And Then Some), and I think you'll enjoy it on The World of Stuff. Hopefully, it will encourage commenting, discussion, and "first post" comments. That would be awesome.

If passed by the House of Representatives, H.R. 888 would be a grave insult to non-Christians and everyone who cares about separation of church and state in America. Joshua McGee says it better than I ever could.
