Ha! I read Barstow and about screamed.

(booooo) Like he said, in the middle of nowhere. There's been some great advice regarding where and what you want to do. I have to second the PCH (1) drive along the coast. Southern CA, (LA) is better for more 'entertainment' related things, and is just a big concrete city and it sounds like you're going to hit Vegas anyway...It may not be 'pretty' but the Santa Monica/Venice area is fun to puts around for the day. See some of the iconic silliness but you can skate, bike, walk, ride etc around the boardwalk areas. Middle to Northern CA has the real beaches though. Monterrey is awesome and if you do end up in Barstow (rent a car btw..greyhound is a bit shady) then do see the redwoods and go to Yosemite. Especially while you can. Yosemite is one of those breathtaking places and it seems as the years pass by, it's becoming less open to the public because of the ever changing geological state...But to see El Capitan and Half Dome and just spend the day in the 7 mile valley.. It's friggin awesome! So you can pretend your ewoks or jedi in the redwoods (that is where it was filmed

) and see trees big enough you can drive cars through the trunks, or maybe revisit a little Trek at Yosemite.. There's also Agua Ducle in Acton, CA that's about a 50 minute Drive from the LA basin. The Vasquez rocks are huge part of iconic cinema history and it's free and you can go climb on the rocks etc. LA itself IS fun, but again... it all just depends on what you all want to do. If you want to get the full experience, do a little of whatever you can but if you want relaxing...the beach and vineyards ARE lovely. Someone also mentioned flights.. You can fly into LA and then catch a flight to sanfran sometimes for like 40 bucks. Check it out see if it's something you can work with. If you do LA, personally, I like going to Griffith Observatory and going to some of the local prop/makeup/wardrobe and off the wall places, between Hollywood and Burbank. I'm getting ready do this myself in a couple weeks (CA for 5 days, AZ for 4 and NV for day or so then back to TN).. Trying to form my own to-do's as well. Best wishes to ya!
