My wife and I are planning to be in Colorado for a few days on October 6-8. We are planning to spend one day driving around the Estes Park/Rocky Mtn. National Park area.

As we are driving around for the day admiring the scenery I was hoping to stumble across a trout stream or two or maybe a nice little mountain lake with some grayling in it and have a go at slinging a few flies.

Does anyone have any specific suggestions? (Or general suggestions for that matter.)

Thanks.
