Thanks everyone! Glad I could share a little of our fun with you. Hadn't noticed the sign, but it certainly doesn't lie! My cousin said Ferrara is one of only six cities in Italy that still has the original wall entirely intact. It was really cool riding the trail along the outside of it. Once I get the rest of my pictures on my smugmug site, I'll post the link here. No more biking, but it's hard not to drool over the scenery
