We arrived at 9:30 AM and headed for the North Day Use parking lot. We were the second or third car there. We did not plan to see the shut-ins but instead put our chairs in the river via the access trails by the North Day Use side. We were able to choose any picnic table and setup our future lunch spot. I don't think but one other table was used the rest of the day, because most people that parked here walked to the shut-ins. The early afternoon was very peaceful and we were the only people in that section of the river. By mid afternoon the parking lot was full and there were then several small groups of families in the section by us, all very polite and friendly. Don't know, but imagine the shut-ins were busy with people due to seeing all the cars drive in that direction. We left by 3:30 and the parking lot was starting to empty out. Decent vault toilet in this section, if you don't look in it, and flush toilets by the Black River Center.
