Games in Vegas year around?

[Python49]

Friend of mine said while he was out in WSOP over the summer he talked to some people that worked there and was told that outside of the WSOP, the games were usually really slow throughout the year. Can someone who lives in Vegas give their experience? He said moving to Vegas for poker isn't even a good idea and much better to move to LA. How are the games at 2/5, 5/10, and 10/20 level? Are they mostly filled with regs?
