The Bozeman show?

Does anybody know what the age limit is (or whether there is an age limit) to the Bozeman show? I've tried to contact the venue "Filling Station"  and the "Bozeman Dept. of Culture and Entertainment" to no avail. I've been hosed by the age limit before, just don't want it to happen again. 

Thanks

Regretfully, according to our records, the show is 21+. I would try calling the promoter of the show, Grant Gilmore (if that is his real name!), at (406) 209-3556. Or make your way to Spokane, which I can attest IS an all ages show.
