I just received a call from Grumbines which is the Camping World Dealership in Harrisburg Pennsylvania. They just moved into their new building about a week ago and extended to us a special invitation to visit their facility. They will be in the midst of a 10 day block party featuring food, seminars, and live music. We have planned a Montana Owners Club visit on Saturday, June 21 @ 10 am. It is about a 1 hour drive to the center from the campground. I will have more on this visit at the Meet and Greet on Wednesday night.
Then, since you are so close, you can visit Hershey's Chocolate World which is 6 miles away and about a 9 minute drive.
