Goose Hunting Blinds

[Tenpoint]

I plan on doing some field hunts for Canada geese in September. I usually just lay in the field wearing my cammo amongst the decoys and put a bit of hay/straw/corn over me.

Last year I was getting alot of birds circling high and then movng on. My question is: Are coffin blinds or round bale blinds worth the investment?
