I live a little over an hour away from the hotel. Will anyone be posting specific plans so I might be able to drop by for one of the "events"? I can't commit to anything, but I'd like to try and make it.

BTW, if you're still trying to come up with free events, there are the old standby "Bigger or Better" and "Digital Scavenger Hunt".

Bigger or Better
Each team starts with a small object (say, a paperclip) and walks/rides around town trading it for something bigger or better. They in turn trade that item to someone else, and so on. The team with the biggest/best item at the end wins. (I don't know how well this would work in a city setting.)

Digital Scavenger Hunt
Someone(s) comes up with a long list of "things" (for lack of a better word) and each team tries to take a digital picture of as many items as possible.
