Other than some rattlesnakes at or near my feet, and one crazy skunk that would NOT leave me alone, they didn't get used for much but plinking.
In PA, we don’t “register” weapons. The only time you need a “permit” is if you carry concealed.
If the weapon is in plain sight, like on the dashboard of the car, “theoretically” it is NOT concealed, and therefore legal.
Now, that will cause a boat load of controversy. Thing may have changed and I’m not going to discuss it past this point.
I used to go everywhere on my BMW, complete with a saddle sheath, rifle plainly visible from the back of the bike. It was funny, on the turnpike, I’d pass Joe homebody with all his kids in the car, and all of them would point fingers and bother dad. At the rest stops, the ninnny nannies would pee themselves and run to find the nearest LEO.
PA State Bulls at that time were professional. “Yes ma’m, we can see he has rifle, and that’s as it should be.”
The looks of confusion were priceless.
