Actually there is one more climb (better yet a series of climbs) I forgot to mention. This is also in a place you would never expect, aka bum f@#K Missouri (fyi Missouri is not flat). We were doing a ride from St. Louis to Jefferson City MO (about 130 miles). I am pretty sure it was Mo rt. 94. About 70 miles into the ride we hit a series of steep (probably >10%) that seemed to never stop. I think we did 10 or so in a row, and it was up around 90 degrees. There was also no breaks between these hills, you could feel yourself getting pushed into your seat (like a roller coaster) at the bottoms, and your 40 miles an hour didn't get you anywhere up the next hill. Not much elevation on them, probably less then 300 or so feet, but it was like climbing a wall. That combined with the heat and lack of water, and a 130 mile day made it real difficult.
