Though I live in Baltimore, a three-hour drive from that spot in western Maryland, I have been through the great small town of Grantsville dozens of times over the last 25 years, mostly on fishing trips to the Casselman River, with stops at the Hill Top Fruit Market and the Shop N Save. I get off Interstate 68, turn north on 219 (or Chestnut Ridge Road) and stop at the traffic light at Route 40 Alternate. The area is never congested. I have never sat through more than one change of the light. That’s why I scratched my head at the idea of a traffic circle there.
