Ride the rails on the G-Scale model train at Gabis Arboretum. The Purdue University Northwest Gabis Arboretum serves as a living laboratory for education, research, conservation and engagement with the natural environment. They have a Garden Railway that spans two full acres!!! The model trains run Fridays, Saturdays, and Sundays from May through October 10a.m to 3p.m. I'm always glad to have the opportunity to visit!
