Here in SW MN one of the problems with the heat,, and the drought, is that the lakes are turning green and smelly early.
We had very little snow last winter, and not much rain so far this year.
Around here are lakes are all polluted by agriculture runoff. When you get a hot dry year like this they all turn to **** quickly.
I have reservations on a lake for the 4th. After that I will probably stick to campgrounds that are on streams and not on lakes. The lakes are going to be full of Blue-Green Algae and it is toxic.
