I'm planning my own Gettysburg ride, though I don't like Wyman's route up Falls Rd. My route goes up through Greenspring towards Hampstead etc. Probably do this Friday, long weekend rides are tough with kids, little league, etc. Hoping to ride from Quebec City to Albany in early June. Did 700 for April, May will probably be less but June should be heavy miles.
