The one about the rolling hills---10 hills of 100 feet-- is another issue. One of the reasons why the appalachians are far, far more challenging than the rockies is that, over the course of a full day riding in Kentucky, or Tennessee, or Vermont, one may ascend and descend ten, twenty, maybe thirty hills varying in local relief of 100 or even 200 feet. That easily adds up to thousands of feet of climbing, which easily exceeds the local relief of the vast majority of rocky mountain passes. And to boot, the grades on these "short hills" is often in excess of 5%, so its not surprising you end up bagged out at the end of the day! Arf.
