I’m on the road in the “rust belt” again, although mostly not to the same places as last year. My first major destination is Columbus, Ohio, which hosts the American Philatelic Society’s big annual stamp show. I’m taking the same route north through Kentucky as in the previous trip, just with different sightseeing stops. This is just after entering Tennessee on I-26: This huge excavation is in Pikeville KY, where they cut through a mountain in order to reroute the river which had a habit of flooding the town. While they were at it, they rerouted the main highway and railroad. The town loops behind the mountain in a U and “emerges” on the left side. The river, highway and railroad all pass in front of and below where I’m standing. A marker here claims that this is the second largest excavation after the Panama Canal.
