It didn't take long to get my twin sister in on the action—she's impressionable, and I gotta say, the NPS Passport makes a good impression. We missed our trip last year due to the annoying confluence of moving, her training for the New York City marathon, and that part where sometimes you just don't get it together. But when she came down to Baltimore for a weekend getaway, we were determined to hit the Johnstown Flood National Memorial in Johnstown, Pennsylvania, just outside of Pittsburgh. I didn't know much about this flood, but at less than four hours away, it was ideal. After a little reading, the field trip started to get real exciting, because this flood is the story of infrastructure, state, capital, rich people building their own private country club getaway without a care for the multitudes living below—pretty much all my favorite stuff to get angry about, all in one visit.
