My two cents for what it is worth. Cedar Park is a fine place to get an in-call.
It just depends where. There are parts of Cedar Park that are Travis County. Lakeline Blvd/Ridgeline is the county line.
I live up here so this is me speaking from experience Also there are plenty of people in the Leander, Georgetown, Round Rock, and Lago Vista area's that would love more providers in this area. The Domain is too far. Also if you choose to come this far north stay on the east side of 4 points and Anderson Mill.
If you would like more info feel free to inbox me. There is a lot of misinformation out there.
There is plenty of money here.
