California! Over 10% of the nation lives there! Some of the reasons are the beautiful coastline, mountains, deserts, yosimite park, beaches, and weather in particular in Southern California. There are times in the month of February one can go snow skiing early in the morning, drive 2 hours in the afternoon and lay out on the beach!
The state is so big there are towns that fit everyone's personality (small towns, large cities, mid-size towns, unincorporated areas, towns like Big Bear in the mountains, desert cities such as Palm Springs,Nappa Valley for wine lovers and of course Beach cities!
There's always something to do especially near the major cities. Los Angeles/Hollywood, Beverly Hills, Orange County, San Diego, and San Francisco. (Too many attractions to name!) http://www.visitcalifornia.com/
