83 mile (or 62 mile) loop has sweeping views of fields + farms, old houses, cows + horses, lots of quiet roads, a waterfall or two -- and some fun downhills. See www.roberts-1.com/bikehudson/r/east/gt_columbia - routeID [bhve4c] - for lots more info, map of full loop, variations, and detailed cue sheet. We usually use this in an 83-mile loop with sections A + B (search Bikely for bhve4a + bhv4cb), or sometimes in a 62-mile loop with Variation AB (search Bikely for bhve4av).
