I'm in the process of making a duck blind out of PVC pipe and fittings. The entire project cost me around $50 (with paint and glue). I like it because it doesn't weigh much and if I need to move it to the other side of the pond I can do so by myself. As for the squeaking?? I'm sure it would if I hadn't glued the joints well.
I would neveruse it for deer hunting, because it does sway with the wind blows.
and that's my 2 cents
