These guys have you right on track, fish up the rockies from the springs and then down the rockies from Vail. Heck bring a nice little 3wt and hit clear creek along hwy 6 heading down in to Golden and you will have made the best fishing loop in the state.
gheez Im jealous and I live here.
PS I fished Pumphouse on the Colorado Saturday and those fish were well fed and they hit hard. I had several 14" Browns bend my 6wt over like it was a 3wt.
