I am in the early stages of planning a cross-country trip from Cincinnati to California, and am just looking for any advice/suggestions from anyone with experience with this kind of thing. I am planning on going with three other friends, and we are trying to go to as many national parks as we can (especially trying to get to Yosemite) and some other places. We love hiking and camping and that sort of thing, so any ideas/advice is hugely welcome. I am wondering if anyone has any advice about the pros and cons of renting a car vs. driving for this sort of trip. If you have any suggestions of must see places along the way, please let me know!! ANY advice is greatly appreciated!!!
