Solveg, I bet you can do the 70 mile route, and if you want to, I say go for it! It's a great opportunity, and I wonder if you'll regret it if you don't?
Thanks for the offer of cooking pasta at your cabin - I'm ok with either way, or really with any plan as far as food goes. I'm sure we'll figure it out. Will wait to hear what the others have to say.
