Trust me on this here in Maine we have mosquitos but our state bird is the Black Fly!! Soooooo much worse!!! Used to cold weather as well
Honestly the reason we ended up in Minnesota is the SWMBO is a MN native and her parents still live there and they are both in their 80's. She wants to be closer to them to be there to help out as they age. ( She finally admitted this during the search ) We pretty much ruled out anything in Northern MN due to many reasons the biggest one being there's a lot of motels, inns and lodges fighting for the same dollar in the busy parts and the ones without a lot of competition were too remote for us.
As I detailed earlier we couldnt find a decent successfull campground in our price range. They either were failed or failing. Example to find a campground with the income of the hotel we chose would be around $2.5 million. The most income we could find in our $500k limit ( and within our geographic requirements ) was like $14k a year.
Turns out campgrounds within our means to buy are more a labor of love than a money making one. Money isn't everything but we have other plans and we need the money generated by the business we buy to provide the capital to fulfill those plans.
