I run the Range Listings website at http://rangelistings.com/ which is my attempt to get a map of every US state with markers for shooting range locations, plus a little extra info for each range. The idea is to make it easier to locate shooting ranges for shooters who move into a new area…or just want to discover other ranges.
It's a hobby project, so when I have a little time here and there I try to keep it updated. There are between 3 and 4 thousand ranges on the website.
Found out about this website since the person who runs this site posted an ad on rangelistings.com. Cool idea. Hope to see many more people sign up!
