Intimidating the locals

So we've vacationed in the little town of Hessel, Michigan for coming up on forty years now. Just down the road a piece is Cedarville. Sometimes, it seems, the two villages get a little bit fractious with each another.
One year when my sons were teenagers, there was some small dispute between the towns during our vaycay. Apparently Cedarville was trying to muscle in on Hessel's action, you see, trying to take over an antique boat show which Hessel had hosted since its start. A few Hessel citizens were complaining about that one day as my boys and I stood nearby.
After listening to the complaints for a couple of minutes, my sons walked over to the tiny crowd. Both of them were punching fists from one hand into the open palms of the other. My oldest grunted to get their attention. "Uhmm. We're from Detroit. Ya want us to take of this?" he asked.
The four people looked at them and replied nervously something like, no, that's okay.
But Hessel has kept its boat show ever since.
