Brrrrrr 19F at 6AM today. Yesterday's sunshine & breeze left local roads dry, so I rode my Grand Jubile & only had to dodge a few frozen puddles. By lunchtime it was a balmy 31F & on my ride home for lunch, a pitbull ran at me from across the street. I sped up & he passed behind then wheeled around & fell in next to my rear wheel, fixated on my rapidly churning right foot. I yelled "No, bad dog!" & that got him to look up at me & hesitate. Then his owner yelled from his porch & the dog gave it up & trotted back across the street. A passing truck blew his horn & scared the dog back into his yard. I pass this house daily & never saw this dog before. Hope he was just a visitor. Don
