I thought of buying a couple to see what was knocking down the bird feeders, but then my dog cornered the possum and I knew then. I admit, I agreed with some of the reasons they are banned for hunting, in the following states:
"Trail cameras are legal in most states, but there are some restrictions on their use. For example, in Nevada and Arizona, trail cameras are banned for hunting purposes. In Montana, Utah, Kansas, New Hampshire and Alaska, the use of wireless or cellular cameras is prohibited during the hunting season"; that probably includes using drones.
Anyone that needs 50 or more, probably is using them for poaching. A couple years ago, the authorities arrested a group of poachers in Cowlitz County, WA. It was a costly experience on both sides.
