huge number of hot chicks come in from Phoenix, Tucson, LA, OC, SD, Bay area (although the Bay produces the fewest of the lot) every weekend. Typically they aren't there during the week though so I don't know what TRS is seeing. Wait until the weekend for the real ass to show up.
However, the best for the single guys are the midwestern chicks. They typically venture to Vegas less frequently and are completely overwhelmed by (i) the money; (ii) Vegas; (iii) the clubs; (iv) the drugs; and (v) the freedom from Joe Lunchbox Boyfriend; and completely whore out under the cliched "What happens in Vegas stays in Vegas" mantra.
The chicks from the west coast are used to Vegas and the partying.
