I lucked out.  I was wanting to visit the headwaters of the Mississippi it was getting late in the day and I didn't have a reservation.  Lucky for me they had one site left with no electricity which was perfect.  I was near the bathrooms and shower house, both very clean.  Campsites are close together, but wooded making for a little privacy.  Overall Itasca State Park is very nice with lots of trails and a scenic drive.
