Depends on my mood and who I am with. If I am with the family, I almost always want to go where there are the least assholes and people possible, like to any beach without loudmouth punk kids, or to the Sierra Nevadas out here in Cali where i can enjoy the redwoods. I like the beach and need trips to it, but nothing soothes my soul and mind like being out in the wilderness. I guess if i lived there permanently, id want to go to the beach more, or vice-versa.
If i am with friends, there is nothing better than watching a bunch of women in skimpy suits. That said, we could cock-fest it in the backwoods, and i'd be happy if it meant not being around retarded people.
There are tons of places i've yet to visit though, so my answer will be limited to mainly Cali, Oregon, Idaho, some of Washington, Mexico, etc.
I like good tasting food too, so any beach or area that has good restaurants, bbq, or whatever.
