Been to the USA quite a few times and loved it.

YOU HAVE to go to Magic Mountain in LA if u can. The rides are the best in the world. Take a change of underwear.
Magic Mountain is 15 mins from LAX internatioinal Airport. I hired a 5.4 litre Mustang with a mate n had a ball.
Even got to go for a ride in a Police Persuit 460 big block Ford one night with a few of the local police. These 2 x cops were having their dinner at a truckstop and i kept telling the cop our police cars were much much faster in Australia.

They said they would give me and my mate a lift back to our hotel 5 mins away and show just who had the fastest police cars in the world. The 460 big block did 90 mile an hour in first gear, and had 2nd and 3rd to go.FARK !
I told him he was the winner. The cop exclaimed "ofcourse, no one beats the California highway patrol". Nice guys/nice cops,huge guns and great memories ! Even Disneyland is a blast. But sore legs after 10 miles of attractions to walk around to !
