A year or two ago, we (Wisconsin Traditional Archers) had the same thing happen at a Deer and Turkey Classic, the biggest annual consumer sports show in the state. On top of that, the person heading the cross gun booth, was an ex student I had in a university class about 25 years previously. We became friends and after he graduated, bird hunted together a time or two. We got along, though we did make "No Crossbow" stickers available to anyone who wanted one.
Their booth actually received a lot more traffic than ours. Crossbows had just been legalized in the state, and folks were flocking to buy them.
