I love Peshastin. But I have a hard time talking people into going out there to climb. I don't know why "old school" should have anything to do with it (although I admit this was one of the areas where I did some of my first climbing, in the early 90s)--if it's good climbing, it's good climbing. Plus, as you say, Lowell, you virtually have the place to yourself!
I had a similar experience last spring. When we pulled in about 10:00 AM nobody else was there. By the time we left at the end of the day, only two or three other parties had come out to play.
