Hi Bill,
You no doubt will get alot of good info, as there is a great CO, and pro-CO contingent here.
After spending 3 weeks in Denver over the past three years, I feel as though I have a decent perspective.
As you know, there is little outside of Denver to the Northeast along 70 towards Ballyneal.
So, you need something near the airport or in greater Denver. I played CommonGround last September (holy crap it was cold...and it was 75 in 9/08 for shit's sake). It was really cool. I'm looking forward to trying it again in 9/10. You will not remember many vistas or be hit over the head with architecture, but it is solid and wide. There are a few other publics in Denver that are also worth seeing, but I have yet to give them a shot. I plan next September to hit Riverdale Dunes, Murphy Creek, and a couple others.
If access isn't an issue, I would heartily recommend both Colorado Golf Club or Pradera down in Parker, about 20 mins south of the city.
I felt I had to respond considering the Avery Brewing Company (Ft. Collins, CO) "Keiser" beer I am drinking right now during the Bruins-Leafs tilt....if you find this beer in a store, buy immediately!!
