Sandy ... if you're interested, I would be willing to exchange a copy of my last year's 4-Day East map for a copy of last year's 4-Day West. I mapped the route in Topo and have my altimeter profiles also if you'd like them (to give you an idea of the 4-day East terrain). It's a comfortable ride. You'll enjoy it. I hated the safety flags however and almost wrecked when I stopped because I'd forget that the flag staff was there!
