I'm not sure where the first one will be held at (maybe my office, but it's out in Lakeway - about 30 minutes from downtown) so I'll let Warriors know, in case you want to come hang out.
There are a lot of marketers around here, and I'm sure some will even fly in for some of these mixers. Knowing David and the rest of the folks starting these, I'm sure they will be tons of fun.
I'll update this thread when I find out more.
Let me know if this is something you'd like to attend
