In the back part of the site away from people there is an area where people have definitely been target practicing. Lots of shotgun shells and bullet casings on the ground back there.

I’m here now for 4 weeks and I never heard one gunshot.

You are likely hearing the air cannons used to keep critters out of the nearby fields. Been here several years and occasionally some duck or coyote hunters my pass through, that's about it.

I was there for a week, and was very quiet...never heard any gunfire
