We would like to make our first trip to DL. We are out of school the 17th of May. When would be a good time to go crowd wise? I have read about end of year school trips and grad nights with the locals. Fourth of July weekend show the CA blockout. Am I better going end of May-June or 4th of July? I really want to spend 2-3 days there. We will be driving down from San Francisco.
