We played Last Night On Earth yesterday and got a little confused as to whether or not the Signal Flare was a gun.
I had Father Joseph in the Gun Shop and I thought that the Signal Flare was a gun (it looks like a gun, you fire it) which meant that I could pick it up but not use it. My opponent thought it was not a gun which meant I'd have to go to the Airplane Hanger to pick it up, but Father Joseph could use it.
