To answer your question, Yes sometimes it 'can' be bad for hunting. In my opinion it depends completely on the area & situation. I have friends who swear by the "Cattle & Deer Don't Mix" motto. I've hunted plenty of pastures before, and many times they're the best places to find that big ole buck, especially in high hunting pressure times. They get pushed out of the big woods and hang-up in the small patches in timber or grass patches, which are often times overlooked.
