GORGEOUS scenery in the deserts & mountains (you can even take an aerial tram to the top of the mountains and it's 30 degrees colder up there. It's crazy!)
Lots of out doors activities to do
Beautiful architecture (I love mid-century modern houses and they are ALL over PS.)
Insanely cheap drinks at all the gay bars
Tons of great restaurants
Lots of clothing optional "resorts."
Lots of great second-hand & consignment shops where you can find the BEST vintage chotchkies, furniture, nick-knacks, etc.
*I have a bunch of friends who live out there, so I have places to stay for free. I just have a blast going... when its Summer and like 110+ during the day time, the nights are like 80's and it's AWESOME. Skinny-dipping all night, lounge by the pool with cocktails, hang with your friends... I love it!
