Ice cream (and pet) lovers have made Flat Pennies Ice Cream in Bay City a top choice. Owner Jim Ross creates homemade house-made soft- serve ice cream in a little cabin next to a SOO Line caboose. Visitors traveling with pets can take advantage of the “pet rest stop,” a pet-friendly area where furry friends can stretch and enjoy a woof wafer. Flat Pennies is so popular, engineers have been known to stop their freight trains to order a cone and lunch to-go.
