His question, "How far from sunset can you see Venus?" Using the neighbor's fence as a horizon (with a personal correction for it not being at my eye level) I was able to preset and view its meridian passage quite often for many months until it got too close too the sun. Being in in Indiana (corn and bean fields raising the humidity during the summer), and downwind from Lake Michigan, there are many days with anything from a slight haze to cloudless yet milky-white skies. The upshot being if the humidity is high in either the lower or upper atmosphere (contrails) chances of catching Venus are slim. Given a clear blue sky with no contrails it pops right out if you look in the right spot.
