Twice today I saw a chap riding a trike. The first time he was heading down a hill towards some lights, at which he turned left most expertly by leaning out with righ leg hooked over top tube, or so it appeared.
A little later I saw him again, riding past my house. I thought he said "Hello Peter!" to me as he went by. I said "Hello" but he'd gone. I didn't recognise him.
