Hi, 3 of my friends and I are planning to take a Road Trip in the Summer after our senior year of high school. Our trip isn't planned until Summer '13. We all live in North County San Diego. We have planned to go up and down along the coast in one of our own cars (or would you suggest renting a car?). We want to start from here (Carlsbad) up to either the top of California or to Vancouver, Canada. We will all be 18 by then so we don't want to get too risky with the places we go to. We definitely want to go to LA (fashion district, Venice Beach, Santa Monica), and San Francisco, we aren't too sure about any other locations though (what do you recommend?). We also want to visit many different shopping locations both cheep like thrift stores and more expensive places.Also we will probably be staying in motels or cheep hotels along the way, we don't know if there are any hostiles along the way as well. We are totally open for any suggestions on locations, dining, and accommodations so please feel free to leave any feedback and advise but please remember that we are teenager and are not rolling in dough. Also since we are planning of driving back down we can stop at different pllaces on our way back home or take different routes to different cities.
