What an awesome trip - I'm so jealous! I've been trying to convince my husband that we should ride the Katy, but he's convinced that since it's not an all blacktop trail, it wouldn't be any good. We rode a small stretch of the Mickelson Trail in South Dakota several years back and never got a chance to coast on the unpaved surface - and he's completely set on riding road bikes with the skinny road tires. So how was the ride? (Besides the hilly section!)
