For me it was a couple girls about 12 years old walking a goat on the MUP. They had it outfitted with saddle bags. Unfortunately the goat was not used to bicycles but I narrowly avoided it anyway. I thought that was the most unusual until yesterday when I was riding the towpath in the Cuyahoga Valley Natl Park south of Cleveland. Encountered an older guy and his wife walking three dogs. Not so unusual, then I noticed the macaw on the guy's shoulder. Never seen anyone take their parrot for a walk before.
