Wow, a lot of cool ideas. I forgot to mention that the t-shirts weren't cotton, all the clothing is going to be synthetic with the exception of the wool sweater. I was looking at the spread today, I could get by with two Panniers, I have four. I keep rereading this book that says leave room for the stuff you'll purchase on the road. So I think of using the front panniers for such items, but this morning I was like thinking this is daft.
What about carrying extra water? I have an MSR water bag it's the 2 liter, and I have several Nalgene bottles. I stumbled on an idea this morning about frozen OJ with a little salt mixed up as a "sports drink." The thought of not having to cook is a cool idea. Maybe it is this romantic notion of setting up a tent and getting to cooking a pot of noodles for a meal at the end of a ride, it just sounds cool. Of course after a hot long afternoon of riding who'd want to eat a hot meal?
My other concerns are just keeping the cost down.
