Touchdown! Greaser!
I was on short final at a large fenced in highly secure delta at night. It was probably a coyote or deer. Neither I no my CFI saw the animal, since it was dark. But someone on the ground saw it walking between the lights. All I knew was someone got on the radio and yelled "Go around! Go around!"
Don't have to tell me twice. Someone on the radio yelling "STOP!" or "GO!" as far as I'm concerned is an ask questions later situation.
I once saw a completely fenced in airport with at least 15 dear running all over hell trying to figure out how to escape. The guy at the FBO just sighed and said they never had a deer problem until the fences were built to keep them out and now they are constantly stuck inside.
