Ok LEO, after yesterdays drone passover (seen by the trust property owner since I've been sick in bed), the cannon was for 4th of July Celebrations and nosy neighbors to scare them off. The plant is legal and so is the cannon. Have a nice day because the photo was for entertainment purposes only. Don't go trying to get one of those bogus terrorist letter things for a sneak and peek. Just ask nicely and all will be willing shown. Nothing illegal here, now you can move on.
