the noise is the noise and to those who would like at least one day without hearing it when they are outside their homes, it matters.
How many shots do you typically hear from hunters on any given day? They are usually few and far between. And populated areas are usually bow-only anyway.
If noise is a problem, why are gun clubs allowed to be open on Sundays. A pistol range and skeet shooting range produces a lot more noise than a handful of rifle shots a day.
Also, can't they allow Sunday hunting on your own private property? I hear that people who open their land to hunters don't want it. But, what if it is my own private land? Or SGL? It can't be because it would be too hard to enforce. They have streams that have certain sections that are open to catch and release, fly fishing only, etc... and that can be enforced.
