After the first few dams the boys developed a method of going over even big dams without stopping. The bow paddler jumped out and pulled the canoe onto the dam,the stern paddler then jumped out and pushed,the bow paddler jumped in as soon a the canoe hit water on the other side and paddled hard, and finally the stern paddler pushed the canoe the rest if the way and jumped it. it was like a ballet an usually they didn't even get their feet wet!
