Well, I got busted bigger than Dallas last night:
I was sitting in my usual parking lot, using a free wireless connection, when I saw a truck about 10 spots away pull out of the otherwise empty parking lot. I didn't think anyting of it until about 15 minutes later when the same truck came back and parked 2 spots away from me. The guy looked at me and saw I was using the computer, but he didn't say anything. He got some things out of his truck, and then I heard a door open right behind me. I looked at the door and saw that it was SMC--the same name as the router I was using! While trying to look inconspicuous, I quickly turned off the laptop and drove away. In the rear-view mirror I saw the guy checking something--probably his network. Naturally I hadn't done anything at all to their system, but I figured it would be better not to be in the area any more last night.
It's not a factor anymore as we checked out of the hotel this morning to move into the apartment. I don't know where I'll connect to post this entry, but I'll be favoring openly free services such as Panera Bread or atlantafreenet.org. [Update, 2150: I couldn't find anything free, so I'm posting this from outside a Starbuck's. Cost me $10 for 24 hours of access, but maybe that's better than sneaking around parking lots]
I called Comcast today and the first available install date is next Monday. That means we'll have to find some wireless connection, free or otherwise, closer to our apartment. Lord knows I can't be without the internet for 6 days!
