Hey everyone.
My friends and I are planning to go on a road trip later on this summer, and were wondering how feasible a trip from Indianapolis, IN to Seattle, and then to LA and back is, and how long is a reasonable time period. We mainly want to visit these two places for a couple of days each, probably drive along the coast, and maybe see a couple of other things (i.e. Rushmore, the Golden Gate Bridge, the Redwoods).

Also what sorts of things should we do while in these cities.

We were also wondering what kinds of vehicles are best, and any other suggestions that would be pertinent.

Thank you very much.
