It's possible to climb and when the sun comes up be in sight of another hunter. I don't understand anyone squirrel hunting during deer season on public land. I know I would be angry if someone was shooting squirrels. I love to hunt and eat squirrels, but I hunt them in Feb or on private land. It's called consideration not many today use it.
That's the only option most small game hunters have 90% of small game season. So unfortunately that's something you have to put up with. I run my squirrel dogs on the forest all deer season and so do countless others.
