Gun.
I thought about putting openings on the sides.That one is 18" x 60".I have a great view of the trail out front.I put a full lenght bench with foot rest's in it.Plenty of room for 2 people.

I hunted from a tree stand there last year.Once the leave's drop,I can see a long ways.I built the blind because my 11 year old son wants to go with me.
