This is how I've hunted for 26 years in Minnesota. I drive, scout, and ask for permission every September before fall hunting season, and again in April before spring turkey season. I have not paid a penny in cash to do it either.
It takes time and will power. But it pays off because I have a nice milk run of private land to hunt on every year. Which is mostly untouched by other hunters too.
Anyone can do it, you just have to dedicate yourself. I imagine you could do it in other states like Iowa too.
