I would like to put my 2 cents in on this again but I won't have time till the weekend. Until then let me leave this comment to consider.
Back before highways with marked exit ramps and road signs, a few here may remember Rt. 66 as I do. But even before that, when anyone was traveling , if they had any intention of returning to where they started from they would periodically look back over there shoulder and take a good long look. This was called "checking your back trail". Why look back? Because, going the other direction looks entirely different. Landmarks are reversed and even appear completely different. Walking a familiar trail, in the opposite direction than usual, will appear different. It's not a big deal.
