I'm pretty slender so I get cold easily, but everyone I was with said it's uncomfortably cold some nights at the Gorge. Last year the first night was cold but I was fine the rest of the time. 2009 was the opposite of 2010, I slept without my sleeping bag in a t-shirt and shorts. I don't think it got much below 65 degrees at night that year.
Oh man just want to be in the sun at Sasquatch right now.
Holy SHIT, that is hot! That's 90+ F on Sunday and Monday, right?
2009 was really hot, but to be honest I prefer that to bad wind/rain/sleet, if the weather can't be ideal. The wind and rain at the gorge is brutal, but the sun is the same everywhere and easier to prepare for, IMO.
