There's also this:
A common ride for Mrs. Grouch and me is to coast 2 miles down Jungs Station hill to the Katy Trail, ride into St Charles for breakfast and ride back home. Obviously, the last two miles back is uphill. We ate a meal, however, at the low point of the ride so we have to work harder on the return trip than we benefit on the way out. Is that fair?
