Oh man, ya all the lakes are terrible in Az and the chicks aren't actually hot here at ASU at all. You should definitely stay away from both.
Having not lived anywhere else that I really wakeboarded I am used to the lakes here and love them. If you live close to ASU you'll have about a 30 minute drive on the freeway to Saguaro. But generally to get good water you have to get up early or stay until later. (For some reason my back almost always hurts until we have 30 minutes of daylight left.)
Oh, and the chicks at ASU are unbelievable! It's the land of supermodels here! And they love to go wakeboarding!
What I'd reccomend Ryan, if you end up coming here, is check the find a third section and start finding some people to regularly ride with. Most people I know, myself included, have a strict policy that you can't bring an uninvited friend along . . . unless she's hot.
