Only use gps as a reference. My uncle and dad was running back on smith one night with no moon. He was using the gps and went into the buck brush. Could have been worse. Running at night I watch the tree line and only fish lakes or areas I'm familiar with. I hit a tree on little bear one night in the middle of the lake. I'm don't mean a log. Root ball tree trunk and limbs. We went through that area in day light and it was not there. No clue where it came from.
