100 rds is nothing....minimal fire to be sure.  Typical "shooting session" is several weapons...100 rds apiece.

Agree...it's not the Forest Service job to police this...it's the county sheriff.

Permit to Carry and Permit to Purchase handguns in MN is up by several 100's%.....IMO.  I posted a thread about ammo availability a few mo ago....it hasn't changed at all yet.  More people than ever are packing.  Bet you'd be suprised how many and who, once you started discussing it.  I was absolutly blown away to learn who's packing in my circle of contacts.
