I just took one of my 4x8 ice fishing shacks that has a mettal roof on it. Camoed the darn thig, cut shooting slots the length of the four sides. The slaots have doors to close when absent or raining. Complete with windows. We just btowed it into place on a 50 foot cliff overlooking a river and a 15 acre island.
This is for my retired father. Would be awesome if he shoots something out of it. Opening day of rifle season is Saturday.
