Consider Sparky's already talked to. I can get six free scoop (each a $3 value) tokens and maybe a Sparky's patch to give away. That's really the extent of Sparky's giveaways.
I think March 17 is not the best though. People will have mid-terms/projects/finals/etc. due before spring break starts and are more likely to take it easy that weekend. Just my thought. Perhaps March 10 is better.
I'll talk to Kyle and the Ragtag folks about what it takes to reserve space. I know Ragtag isn't atop everybody's list of favorite bars, but they have bitchin' dance parties from time to time (i.e. T/F, Citizen Jane, Halloween, Videology). The only problem I foresee is the proximity to T/F. But I'll talk to Kyle nonetheless.
Sideshow sounds like the place with the most potential.
Who can contact the Garcias this week?
Also, I support tabling the non-profit stuff and organizing this party first.
Go bike yourself.
