I love this time of year - mostly - but today is an especially gloomy and foggy day here in northeastern Pennsylvania. On the plus side, it's my day off, so at least I don't have to go anywhere.
Today we're going to make one final visit to Carbon County, as this is the last of their markers which currently exist. Perhaps in the future they'll get another and I'll be able to cover the dedication. In the meantime, though, I can mark Carbon County as completely finished on my personal marker list, after I finish telling you about today's subject.
Pennsylvania is, of course, the site of many "firsts". Some of these are well known; we had the first hospital in the United States, the first theater, the first subscription library, the first zoo. Others are less famous, like the first completely air-conditioned building in the country and the first license plate to display a website address. And then there's today's subject, which was the world's first roller coaster.
