After our ramble through the Wissahickon, and lunch in an air-conditioned restaurant, my friends and I were refreshed enough to take on the Morris Arboretum in Chestnut Hill.

Originally a summer estate, it became part of the University of Pennsylvania in 1932.Besides a wealth of trees, plants and flowers, every summer the arboretum hosts a wonderful garden railway. In addition, this year it is also hosting the BIG BUGS! exhibit.
