Friday and Saturday was just way too hot for me. On Saturday particularly I think I spent a good 5 or so hours during the day just sitting in the shade as I couldn't hack it. I was also sad not to once make it to NYC Downlow at all during the weekend. I'm usually fine to queue for a while but the two times I tried we were literally sent away after being told we wouldn't be let in due to the priority for re-entrants.
Those are the negatives. The positives make up for that massively. I feel the line up was perfect and struck a wonderful balance of classic alternative music, up and coming stars as well as some really nice surprising pop sets.
