I'll be taking a trip with myself and my two kids (inexperienced drivers - 15 & 17, but experienced travelers). We will be starting in San Antonio, TX on July 21st and need to be in San Diego by August 5th. Have some friends we'd like to visit in Boulder, CO and Salt Lake City on the way out and then wanted to get to the west coast. Would the loop up to Vancouver and then down the West Coast be pushing it too much? How about if we drove from Salt Lake to San Francisco and then down? Does that seem reasonable? Any particular things along the route that we should stop and see - we do intend to see SF and LA along with San Diego (idea is to look at colleges). Then from San Diego back to Texas - I've never driven that - anything interesting?
