The island is absolutely beautiful, the bison amazing and we looked at two campgrounds that were both in great locations, with great spots.  Unfortunately all that beauty can't distract you from the thousands of bugs that are determined to eat you alive.  We had already set up camp, sprayed bug spray and brought out all our anti-bug measures, but none of it worked.  We had to break down camp and leave.  Driving off the island, it sounded like rain, but it was in fact bugs hitting the windshield and front of the car.  I would not come back to camp here, but it's worth a day trip.
