Uguide, the best place to find the sheds are where the deer spend most of their time.
Bedding areas are best, But not good to go in tough Winter conditions.
No need adding more stress to the deer.
I see where you say there is no access, reckon that's why.
Trails to and from feeding areas are good. Do they cross fences? Might find a shed at the crossings. Going over or under fences will knock off a lose bone.
After the bedding areas the next best is the feeding areas. Deer are active, spend some time feeding and will jar off a antler.
