I drive for Uber in my spare time as of a few weeks ago - they just started serving Cheyenne for Frontier Days (and I'm hoping they keep the service on after that, though I'm not sure the demand is gonna be there)

(That is, for the precisely one ride I've gotten.. Something in the backend appears broken and nobody can request rides even though I'm online, and support hasn't been helpful on this >_<)

Can answer any questions you have, but I doubt there's going to be a lot to answer. Signing up as a driver and doing what you gotta do is a pretty straightforward process.
