Took a weekend jaunt to the Tyler Arboretum, a place I've never visited, or known, before Sunday. In Media, Pa., just outside Philly, it is overshadowed by its more famous neighbors like Longwood Gardens, Winterthur and others.

More than 600 acres, this wonderful collection of greenery is now featuring Totally Terrific Treehouses through September. Don't go with the idea of seeing 12 treehouses perched in trees, there are none. It is what the PR director calls a 'fanciful collection' of treehouses, most on the ground, some not even touching a tree.

Still, it's a great way to the get the kids outside and away from the computer screen. Even if they don't like treehouses, it boasts 20 miles of hiking trails and plenty of things to keep the family happy.

More on Tyler Arboretum in the YDR later in the summer as an Excursion.
