It's a rare sunny day that is not climbable for me.
Had trouble a couple of weeks ago when we had a very cold streak, below 0 here in June, talking folks into going climbing. I think NOAA was saying -20 with wind chill for Bishop. Talked Flanders into going to the Gorge, ya Doug. Shorts and tshirts in the sun baby. It did get cold fast when that sun dipped below the rim though.
