Use camo netting too conceal your canoe, garages are a pain,, especially if you build one in an area that has fluctuating water levels.. Bigger isnt always better with duckblinds,, myself and a buddy have a small blind in an area that has several large blinds. we typically do much better than the other blinds. put a 1/3 roof on it,, something you can hide under with brush hanging over another 1/3rd... paint the inside of the blind a dark color.
