If you're looking for some fun afternoon flying, come check out ZDV's airspace. I'm staffing up DEN_CTR each weekday between 2100Z and 2300Z awaiting whatever traffic you feel like bringing. Try the approaches into Aspen, Telluride, or Eagle County, or do a city hop between Denver and Colorado Springs. Or you can check out the border ARTCCs to see who's online, and pick your favorite airline route.
My "official" schedule will be booked into VRoute, so you can confirm there.
