RE: disgusted!
Unless you are hunting a field perimeter, or very open timber/brush country, a shotgun is basically a short range weapon. They can be modified to hit consistently at ranges of about 200 yds with sabots, but more or less they are meant for ashot from 75 to 150yds at most. Within those ranges it is probably more efficient not to have a scope, particularly if you hunt inside timber pockets away from field edges.
My father has bifocals, and when shotgun hunting he prefers a scope for consistently aquiring his target. So, maybe some folks need the optic. I always turn my scope to the lowest setting when hunting tight spots. This comes with discipline though, lots of folks seem to forget that little particular.
