I had a very short ride today: I was at my campsite by 2:00! But my knees let me know I shouldn't try to make it to the next place.
I was put off by the price of the campground that was given to me over the phone, so I looked for other options, but it turned out that was the peak-season price, and the season doesn't start until May 27. I've managed to follow the off-season all the way north from Florida! It'll hit me hard in Michigan, though, I'm sure.
My campsite is up on a plateau overlooking the river.
