At some point in junior high our school bussed us over to Turkey Run State Park. I wish I could remember the exact year or the teachers, or much else apart from me learning never to jump to a wet rock in the middle of a creek (feet went right out from under me, as I probably should have learned BEFORE that). My chief takeaway was that the park was quite pretty, particularly trail 3, which winds up a limestone river gorge.
Now, approximately forty years on, I’m better equipped to understand that many of the trails in Turkey Run State Park, near Marshall, IN, are among the prettiest American places you can see that don’t involve mountain vistas or trips west. And probably they’re comparable to even those, in a small scale way. My kids, who are considerably better travelled than I was at their age, name it one of their favorite places on Earth, primarily because of trails 3 and 10.
