Ranges have always been an AARP convention. I think that the biggest thing is that pre 2000, or maybe 1990, gun ownership was highly linked to hunting. For good or bad, that has changed to people more interested in self defense and long range shooting- both without real links to hunting. That is an issue for hunting and wildlife management- but a much easier and sustainable base of gun ownership. I think it is driven by the rise of CCW and the GWOT/Video-game familiarity with ‘cool’ guns.
And August 1st is the new ‘gate’, right?
