We left the Great Allegheny Passage on our second day, picked up the Chesapeake & Ohio Canal (C&O) as we rolled out of Cumberland, Md. (home to the city-wide happy hour every Friday night) and headed eventually to Washington, D.C.
We had the odd fortune of bicycling every day with rain predicted but never felt a drop until the seventh. On that day no rain was expected but we rode thru a steady drizzle, sat out one shower and rode through another. Nevertheless, every day of the first week was hot and very humid.
