Never had much of any problem getting hassled when out-n-about. But then, the obvious presence of knives, tomahawks, and muzzleloading rifles/muskets tends to ... adjust ... their attitudes before any problems develop.
Altho, we did have one car-load of drunk punks that were ready to cause a problem one time. It was an open to the public living history event. They had stopped by during the day to see the event and the shooting matches. And then came back at oh-dark-thirty in the morning after drinking up a bunch of "courage". We heard them drive up, get out, and start walking down towards camp and our tents/tipis - with the typical laughing/snickering/staggering. Then one of them said --- which one should we burn first! YES, they had a can of gas in hand! But all around them the heard click-click, click-click, click-click. They had half a dozen loaded and cocked guns ready for their next move. They quietly and quickly left. Two were brave/stupid enough to come back the next day and ... chat ... with us about what they had been planning to do - even admitting that they had a can of gas in hand. But they heard all those guns being cocked - which changed their minds. We ... impressed upon them ... how lucky they were and how quickly their night would have changed the moment they started dousing a tent with gas. And how they never would have gotten a chance to light a match after that. 4 of my buddies that were there camping that night were also active duty policemen. We, and they, don't mess around with drunk punks trying to burn the tent we and our families are sleeping in.
There was that one other time a motorcycle gang thought they would ROAR through our camps. A spear through the front spokes stopped the first one in the middle of camp, and a 1770's military unit with fixed bayonnets on their muskets quickly surrounded the rest of the gang. They quietly pushed their bikes back out to the parking lot where the local police had a looooong talk with them.
But basically I and my buddies haven't had many problems. Mostly we have more curiosity than trouble. And we always welcome genuine interest and questions. I've had more problems with the "trout fishermen" here along the creek in the pasture - with their trash and cutting the fences.
