Ok so Navy pier for a Sailor/Pirate meet-up seems a bit expensive for most people (including me!) but the Air and Water show suggested by the lovely lady_saltina in Chicago is free minus transportation! and it's on my birthday Aug 15th :P
Now since I'm not very familiar with the city I was wondering if there would be space for us on North Avenue Beach (which is where the show is supposed to be) to have a pot-luck picnic during the show? or if there was a similar view somewhere that would have more space? It seems to go rather long, 11am-4 pm though we don't have to stay for all of it if it's too long!
