Hi Ron, drop ins are welcome for any unpaid portions of the reunion. The paid portions are meals (breakfast every day, dinner Sunday and Thursday), the day trip, and a hot cocoa bar at the campfire on Wednesday night. Monday + Tuesday are pretty booked but Wednesday or Thursday would probably work. We have a free tour of the historic fish hatchery at 10 on Wednesday (right next to the campground) then the campfire and hot cocoa bar that night so that would be a good day as well as Thursday. Those days after mostly unscheduled so attendees can go tour the area but many will still be in camp. We are at the Spearfish City Campground in Spearfish, SD. We also rented the Snappers Club building in the middle of the campground so drive to that. I expect we'll have people hanging out there most of the time and it would give you a spot to start (and park).
