Me and my friend is coming to Seattle to start a cross country ride on a tandem. our last destination will be DC. We are planning to stay 2-3 days in seattle then to start. We have maps of ACA transame trail but our primary objective is ride from Seattle to missoula mt, for this section, we dont have any map and no idea where we can camp. If you know or suggest anything, that will be very helpful.
