California Flying
California has some very scenic landscape to fly in.
Beware of the Density Altitude in the Summer but dont let that stop you from going places.
Lake Tahoe is a great place to visit, Las Vegas another.
THe coastline also makes for some great flying. Santa Barbara, Monterey, San Luis Obispo, and of course flying over the golden gate into the bay area are all great places to visit.
If you want to continue further north the Shasta Volcanic area is awesome! 14000' peaks with snowcaps are just amazing at sunrise/set.
Beware of the coastal fog which can keep you from landing or taking off. It can sometimes run all the way down the coast. Not much worry about thunderstorms though.
Hope this gives you some ideas.
