i usually set up in fairly remote spots,
but do see people set up fairly close to common walking trails,
if i am walking i generally glass ahead looking for people on the ground, in blinds, and in stands,
generally walk to next point, glass ahead again,
if i come across someone, if i have a secondary spot in mind may turn around, if i am on common trail, i continue walking keeping eye on the hunter trying to make sure he see's me, i keep walking steadily and quietly.
if someone gets upset that i am walking past there spot,
they shouldnt set up over a walking trail.
