Only 12 funders so far. Did Tom Gresham on GT talk about it? How did you hear of it? Sounds like it never got publicized throughout the 2A community. News to me.
I heard Tom talking to Rhonda Ezell (Plaintiff Ezell vs. Chicago), so I googled her and found a photo of her getting an award from an Illinois gun rights group (in 2011) and went to their website (http://www.concealed-carry-class.com/apps/photos/photo?photoid=138706337). I found the link to the crowd funding for building the range somewhere on that website.
