My friend and I want to go on an incredible adventure this summer. We just graduated from high school. Anna is 18 and I am 17; I'm also a girl. We live in Buffalo New York. We want to go to San francisco and see the haight ashbury. We want to go hiking, biking, and kayaking. We'd also like to find some hot springs. We plan to fly into los angeles (because there is a place at LAX that rents cars to 18 year old drivers) and see the city then drive to San Francisco. We want to do this as cheaply as possible. We want to leave Buffalo on July 3 and come back around the 17th. I'm also interested in seeing oregon. Any advice?
