Ah okay that might be it. I could have sworn it was fireworks, but flare gun makes sense. Wasn't doing much good, it was like a scene from "The Birds" driving on Wellborn
It is indeed for bird control. Pretty useless if you ask me though, the rockets just keep the birds in the air until they stop shooting them off, then the birds land right back in the trees. They just need to close that lot for a few weekends and call open season on blackbirds. That would take care of the problem much better IMHO.
