Oh, hi!
I actually wouldn't recommend coming here in the summer. Business is not what it was in the oil boom days, but that is still the myth that circulates and waaay too many ladies show up in the summer. Come in the winter! Like December through March. It's cold, but that's when I do best.
Advertising is mainly naughtynightlife.com (take a look and see how many of the summer ladies are still here - and keep in mind that last winter there were only two platinum advertisers on there). Backpage is active too, but has never panned out for me. There's a forum on usasexguide where hobbyists post some very limited reviews.
The main thing to keep in mind is that there's a really heavy LE presence here with intermittent federal involvement. Be sure to check providerbuzz. Also a lot of guys aren't really familiar with the hobby and don't want to be screened.
You probably want to go to Anchorage and then make a short trip to Fairbanks. Let me know when you're coming, I'd love to show you around if I'm in town!
