For those of you who asked for an update- we did it! With last minute donations we managed to get our booth at our local LGBT pride festival. The 3rd annual Triad Pride only drew about 1000 people all day (they have a serious lack of advertising) but we managed to get some grateful nontheists come and talk to us as well as several new members and some really great discussions. I wrote a short blog about it which also points to our group blog at http://www.GreensboroAtheists.com
which has some video and photos for anyone who wants to check it out. So there's your update! We made it! Thanks for all the comments that I got when asking for advice on this issue- the overwhelming support was really useful when talking to my other members about whether or not we would do this.
