Ok, but remember you asked for it! :-)
At last I mentioned the white water at Ohiopyle and further downriver (toward Pittsburgh) the Sheepskin Trail to Dunbar, PA. The next town is Connellsville. It is the largest town between Cumberland and Pittsburgh. It has a variety of restaurants and stores as well as a good bike shop that is right on the trail.
Leaving Connellsville, you'll reach the village of Dawson. You must ride up to and over the bridge to get to the village itself. It is just a shell of what it once was during the height of the coal mining and coke making era in the region. There you will find a large, beautiful church, restored estate home and remnants of a prominent bank in its time. Somewhere I read that in those days it had the largest per capita income in the world although it is difficult to imagine that in its current condition.
From Dawson to Boston, there are a number of small railside residential communities that were generally populated by the workers in these industries. Curiously, nearly every one has a baseball field and childrens' park that provide(d) recreation for the residents. You'll find various remnants of the coal mining industry along the way.
From Boston to Pittsburgh there are multiple former, large steel mill sites. With the exception of US Steel's Edgar Thompson Works in Braddock, PA, across the river from the trail as you approach Homestead, PA, these have all been closed and demolished over the years and now serve as regional industrial parks. There are but a few remaining visible vestiges of those spralling mills in those industrial parks. In two instances the former steel mills have been converted into large shopping centers (Homestead) and commercial districts (Pittsburgh's Southside area). IF you were want to seek them out there are several of the libraries built by Andrew Carnegie in these former steel mill towns, the largest of which is in Homestead PA a few blocks from the trail.
Well, so much for my travelogue this morning. If you don't already have one, the GAP Trail Guide book ($10) is a worthwhile resource and reference for your trip as well as this bikecando,com website,
