Most of the links on the website lead to an error saying that "Your access to the site has been limited" with a 503 error, at least for me. Even the Terms and Conditions error out - not good to buy a ticket without being able to see the terms and conditions!
I'd agree that it also seems to be a fairly niche market, and with the service alert I saw (Reno to Portland on Friday, and Portland to Reno on Sunday) the timing seems to be oriented towards a weekend in Portland, versus trying to grab the market of people traveling to Reno for a weekend of gambling. I'd think the market would be a lot bigger for "weekend gambling in Reno from Portland" than "weekend trip to Portland from Reno."
