I almost went this weekend, 3/29, but drove up to SF instead. I would really like to join you but next weekend will be only two days of recovery after having 6 teeth pulled.
I got your PM, I'll contact you directly. But check out my JT trip with Douglas Johnson back in Feb, you'll find it in the "trip reports" forum.
You can do the CRHT as a one way, 37.5 miler, if you have a buddy and stage cars at either end. Otherwise yer looking at a yo-yo. I would advise starting at Black Rock Canyon, rather than the East entrance, to avoid a bunch of uphill. If you yo-yo you can plan on 40 miles from Black Rock to Ryan and back. Or 60 miles from Black Rock to White Tanks and back.
Regarding water, I would suggest dropping a water cache at either Ryan or White Tank, depending on your trip. If you decide against this, consider your water consumption to be 2.5-3L a day (with cooking). That'll be 6L+ in your pack, making for over 12lbs of extra weight. Convinced?
I'll chat with you directly.
oh, and bring a bottle opener. ::gaped toothed grin::
