Can anyone tell me if a GPS is really necessary when walking the Colorado Trail, particularly from Waterton Canyon to Copper Mountain? If there is a necessity, would the Garmin eTrex Vista model be sufficient without spending more on software maps? (Is the U.S. Base Map and Trip and Way Point Manager enough?) I don’t want to get lost. But I also don’t want to spend a lot more than I’ve already spent in preparing for the trip. (I do have the Official Guidebook for the Coloraod Trail from the Colorado Trail Association already.)
