Nice route, rode it today. Overall it's flatter (fewer rollers) than many in this area. Two minor directional points of potential confusion: 1. If riding the route counter-clockwise the road sign at Yucca and 170th suggests that Yucca continues north. It's easy to take 170th east as indicated but you are left wondering how Yucca goes north at that point when you are supposed to run into it again further east? 2. While riding east on 170th and looking for Yucca the sign says Washington-Louisa County Rd. instead. Turning north there is still the right move and the road curves east and then north again before reaching Iowa River Road. These are minor but thought I'd point them out to save anyone from possible confusion. Thanks for the route!
