Advice from the old lady:
I'm in Scottsdale about 50% of the time, maybe a little more now honestly. In Tempe you have ASU and so there are lots of beautiful women around here. There are also lots of gold diggers once you get outside the college demographic. Its not quite as fake as Las Vegas or LA, but it's trying to be, lol. People tend to be active and fit compared to other parts of the US. I'd say fit along the lines of San Diego. There are great places to go all over town and there is no shortage of single people.
PM me if you want some pointers. I'm old enough to be your mom, but I was in the nightclub business and stay pretty up on where the good places to go are.
There are also tons of Meet Ups for various interests.
Right now for example I'm working at a local coffee house I like to use as an office. The table next to me has three very cute women seated there working on their studies. They are all thin and have long pretty hair and very little makeup. Smart and fresh faced young women. So if you know where to go you'll do just fine here depending on what you are seeking.
