The G-scale model trains run year-round in the outdoor railway garden at the Morris Arboretum.  They cross overhead on miniature bridges and trestles, pass by waterfalls, and wind through a village of historic buildings. 

During the holidays, they are dressed up in holly and evergreen - and we're a sure bet to bring her grandfather back for a visit. Because, you know - grandpas + model trains = happiness.

The railway garden is part of the vast arboretum, one of a number of gardens and walks.  The weather was good and, as the railway garden became a little more crowded (there were at least 5 strollers parked in a row outside the garden by the time we left), we walked on and went to play for a bit in the sculpture meadow. 

The arboretum is part of the University of Pennsylvania.  There is an admission fee of $10.
