This is for local Delaware County folks. Check out Tyler Arboretum’s Treehouse Exhibit and Butterfly House (opening June 28th). Above is a picture of a tree set up with cow bells. My kids and the other kids that visited this particular tree had a great time ringing the bells. Each of the displays in the exhibit were incredible and fun. Longwood Gardens also has a Treehouse Exhibit, but Tyler’s admission is cheaper and the exhibit is easier to walk around for little guys.
