There's a park with waterfalls on Allen Creek in Penfield also known as Corbett's Glen that my wife and I like to revisit. Reading an thread from 2014 reminded me of our visit last September. It was a Sunday noon-1pm and the CSX trains were flying back and forth. Opposite that, there's a house in the park that has an overgrown garden rail road. There's a google personal "street view" of it https://firstname.lastname@example.org ... 376!8i2688. If you drag the image around, you may see the bridge with waterfall underneath. At the I-490 & Linden Ave.
