Our planned route

http://www.adventurecycling.org/ has all kinds of routes mapped out for cycling across the USA on secondary roads. Since we are starting in Florence, Oregon, we will be following the TransAm route until we arrive in Montana. We then plan to hook into the Lewis and Clark route to go northeast onto the Northern Tier route, which we will follow until we get to the Great Lakes. There's some alternate routes around the Lakes, which we may take (going up into Canada for a bit). Then back on the Northern Tier thru New York, New Hampshire, Vermont, and ending up in Bar Harbor, Maine by the end of August.

That's the plan, anyway!
