A small red light what seemed to be a radio tower light grew larger and moved above the tree line and finally disappeared.I noticed a red light above the tree line across Gull Lake to the west of where I was standing. I was curious because I didn't think there was a radio tower or anything over there. I asked my cousin Greg what it was and he said he didn't know. We didn't think much of it until it seemed to get bigger (from the haze) and it had moved north. It hovered above the tree line very slowly. Finally it went down behind the trees and it was gone. From the time I had noticed that it had moved I watched it for what I would say was five minutes.
