Kudos to Helen Boyd (shameless shill for NYC, can you blame her, she is stuck in Wisconsin with 1200" of snow) for spreading this gem. Brought to you by the geniuses at Improv Everywhere - whose Best Gig Ever mission (documented on this American Life) remains a classic.
OK, here's my idea, which has been churning for a while. Take the Creative Cocktail Hour crowd. And set up a text-message system where, at noon of some regular day (not the third thursday, well let CCH remain as is) we spread the location of a venue to invade (warning the venue so as to have staff and alcohol and maybe even entertainment available). A way to keep the CCH magic going without the corporate sponsorship, parking problems, and huge crowds, spreading the CCH love to other neighborhoods and venues in Hartford, and ratcheting up the undergroundness and coolness of the evening. I have to believe that we would only capture a small percentage of the CCH scene (but it would be a particularly cool percentage).
