Used to live in the UK now living in Chicago. Planning a trip over a long weekend in middle to late May. Is this technically still sonsidered the Winter season. Is there a good vibe and decent crowds ? Not looking for it to be crazy ...just listen to some great tunes and people watch - dont want to go if its going to be dead however. This year can only make it in that time frame. Could go in June but not till 05. Any suggestions would be greatly appreciated. Thanks in advance !
