>>1625756If you have been a really naughty boy and done something that makes all federal agencies initiate a manhunt you against you and they know you're in a specific forest, that's the only time drones equipped with IR/thermal becomes a problem. Thermal and IR are not magic. They don't penetrate through things. A bushy enough ghillie suit will protect you from them.
Dogs are probably the hardest to trick. I don't know how you would do it.
