I’m trying to coordinate a CocoaDevHouse in Washington DC in July. It looks like the 15th is the best, although the 22nd is appealing since it would coincide with the next Iron Coder contest. You can’t beat two for one. :)
If you’re interested in getting together with some fellow Cocoa programmers, either comment on this post or add yourself to the CocoaDevHouseWashingtonDC page.
