Ah, the classic Colorado driving question. SGM may be on to something, but I have not personally tried to bypass Denver with that west I-470 loop. Make sure there aren't any tolls there, as with the east side of the 470.
Having driven through Denver from all different directions, I have come to realize the CO network of freeways is a joke. Give yourself an extra 30min for sitting in stop-and-go traffic, and expect multiple wrecks. Coming from the south, I have always hit bad traffic around Monument or Larkspur, though that was typically Fri night or Sun evening. I've just learned to deal with it, and tune out the traffic with the radio. I am currently commuting from Fort Collins to east Denver every day, and it takes me on average 1.5 hrs each way for 65 miles. I'll be hunting about 30 miles southeast of you this weekend. Good luck with your hunt!
