Sometimes the squirrel hunters get deer up and moving too... its not always a bad idea to be out on opening weekend ;)
You just have to be prepared mentally... one day you might have deer pushed on you and the next you might have a guy walk up under your tree and light a cigarette... gotta take the good with the bad on public land.
Not getting in your business, but if you've never been to Dewey Wills (Saline) on opening weekend of squirrel season, you're in for a surprise. I'm sure there will be other people bow hunting, but I wouldn't recommend getting in a tree. I too will be bow hunting there alot this year, but not the first couple of weekends. Just sayin'.
