The permits can be had just about anywhere, make sure there visible unless you'll have this guy on your ass like I did coming back from the turkey shoot!!!!
If I remember correctly they sell
Resident and non resident permits! I believe we paid about 40$ for ours, come to find out if your bike is registered you do not need a permit- We had a Sheriff walk through our camp, he hung out and bullshitted for a few minutes and that's what he told us after seeing the license plate on one of our bikes
But personally buying the permit is peace of mind bc that's what they're looking for
