They are opening a Sierra later this year in Silverthorne/Dillon---renovating the former Office Max building.
Suspect they will do good business at this location, within a couple hundred yards of both REI and Wilderness Sports.
Many years ago I would stop on treks to Jackson Hole or Yellowstone for fantastic deals on outdoor gear at their original Cheyenne location on Campstool Rd. Still using a Pieps beacon, a Zeiss spotting scope, a North Face tent I got at ~70% off. Days for those deals are long gone...
