A while back a Swiss news website ran a story about Basel's number 10 tram. Traversing two countries (Switzerland, France) and three Swiss cantons (cantons are similar to states in the USA), the number 10 tram stretches over 25.9 kilometers (more than 15 miles)--making it the longest international tram ride in the world. The story mentioned the tram leaving the city and passing through lush countryside along with skirting past multiple castles. Whoa, skirting past multiple castles! that sure got my attention. My bicycle and I had a talk and decided it would be fun to follow along the tram's route.
