The 1933 reunion of the Boyer Association was held at Twin Grove Park located near Lickdale (Pine Grove), PA. Not much is known about the park and much of it is gone. There is a camping resort at or next to the location of the former park. The PDF shows some pavilions for rental and a Ferris wheel, which may be partial hold overs from the park, along with the swimming pool.
From the Twin Grove Campground website, “With a rich history as a country park that dates back to 1930, Twin Grove has 212 RV sites, 43 Cottages, 18 cabins, 4 Family Lodges, 22 tent sites and 2 yurts. They are a 105 acre destination resort campground nestled in the rolling mountains of central Pennsylvania. The property is pristine and full of family fun. The breathtaking Swatara State Park is located just across the street. Perfect for hiking and biking. The ride area includes a full size Allen Hershel Carousel, 60 ft. Garbrick Ferris Wheel, 3 inflatable rides and the Royal Express trackless train.”
