Myself and a few of my friends are planning a road trip this summer as our senior trip. We are planning on anywhere from 2- 20 people and 1-6 cars. We live in the Sacramento area and are planning on starting on heading down to San Diego, to Florida, up to Boston/New York, and take 80 back. We choose the long route because it needs to be simply put, epic. We are thinking of the 2nd half of June and the 1st half of July. Would this be enough time for a good trip? We are all close friends and enjoy driving (one of our stops will be the Salt Flats). Any suggestions or tips?
