Here is a custom Google Map we made, of all the shooting ranges accessible to people in our area (Firestone, CO 80504). Not all of these ranges are public, so many require paid memberships. Many members-only ranges in the area have waitlists up to a decade (yes, 10 years). If you know of a range we've missed, post it in the comments below, and we'll add it.
