After dropping Harriet off at the airport for her flight to New York, we drive to Shark Valley Nat. Park in the Everglades, to pedal the Bromptons on a traffic-free tarmac track. There are alligators, egrets and herons alongside, then we reach a massive observation tower, with views of lakes, mangroves and woods. Vultures circle, and 3 sorts of heron flap from tree to tree below. A stiff breeze stops the heat from being oppressive. Other cyclists on hire bikes admire our steeds.
