by23856 and titleist_03 - I hear ya, often wondered that myself. We' ve all seen deer going horizontal at blistering speeds through stuff you can' t even see through like it wasn' t even there. Good point too on the fence jumping. I am just going by what biologists have know for years and what eyes to the sides do to vision. Cover one eye and reach for something. Depth perception is distorted. I guess it' d be like wandering around your house in near dark - usually not a problem (depending on how many beers you' ve had anyway) Bottom line is deer are rather good at living out in the wild regardless of anything that is know about them. (wow, was that line full of incredible wisdom or what? - duh[:-])
