Glen, Peterson is open till the end of June.
Keita, I live in Albany and fly as often as I can there, which is usually Friday-Monday if conditions permit, but they haven't been recently. Send me your number and I'll give you a call before next time I head out. On light days, the site is really benign with a good LZ. I'd be happy to give you an intro when/if we both end up there. For Peterson, we want SSW to W winds (SW is best) between 3-7 mph. Anything higher and PB is blown out for us. Oh, and bring hiking poles that can fit into your harness.
Stan
