Denver to Vancouver to San Diego
Me and two friends are going on a long road trip in a month. We are leaving Denver, going to Vancouver, then south all the way down the coast to San Diego before going back up to Denver via Vegas. We plan to hit Seattle, Portland, Napa Valley, San Francisco... and take full advantage of any surprise adventures that come our way. We have no real plan, no time limit... we are just going. We are camping most of the trip, mountain biking, hiking and rock climbing.
I plan on taking only the necessities and buying whatever I need from thrift stores along the way. When I leave the mountains and get into southern California, I will take my coats and sweaters to Goodwill and buy t-shirts and shorts.
Any suggestions? Is there anything that I should absolutely take with me and not try to find along the way?
Any good things to see or do?
