Snowing on you at Lakeport is a good probability. First season we had our rig, I was working on it in short sleeves right about this time of year. First camping set up at Pine Ridge near Birch Run in early April and it was cold as heck. Found out what it's like to run out of propane during a cold rain/snow mix, too. Packing up the rig, a thin sheet of ice came off the main slide topper as I was pulling it in and I almost soiled myself.
And we've had to run the furnace in Indian River in May and June, as well.
