Not enough mountains around here, that’s what’s keeping me back!  You don’t wanna go riding off into the mud flats of the river delta, nosirree… that’s a lotta miles with people standing around watching you and saying, “Daggone, man, he must be, what, four or five miles down the road.  Oh, look, he stopped to catch his breath again.  Well, gettin’ dark, best we go home.  He’ll be out of sight by morning, I reckon.”
