My wife and I are flying into Vegas April 18th, we are renting a car and leaving the next morning for a seven day road trip to tour the Pacific Coast Highway. Being from Texas, we never thought of running into snow during this time. We planned on going to Tahoe then over to Redwood National Park at Crescent City, then travel down the coast to Santa Barbara then back to Vegas. Are there any roads we need to avoid, does anyone have any advice on routes we should take. Are we trying to do to much in to little of a time, our plan was to stay one night in Tahoe, one night in Crescent City area, two nights in Napa Valley, one night in Carmel, two nights in Santa Barbara, then back to Vegas. Feel free to make any suggestions, the only thing set in stone is our Flight is booked and our rent car is waiting for us, so all advice is appreciated.
