If you have to pull a saddle off, it's not a deer!
I was sitting in a low box on private land a few years back, on a power line. Heard voices (female) and saw two horses headed right down the treeline. Let them get in front of me then said "Hey!" Had a nice conversation about private land, then we all went home.
Just be careful....I have seen horse riders that don't give a hoot about hunters and don't wear bright colors. I'm surprised no horses have been shot yet.....The deer don't mind the horses, they just might help ya out!
