It's not surprising that Jock is well known for his photographs; he works hard making and distributing them. My favorite work of his, though, is his conceptual piece. (There's only one as far as I know.) Years ago Jock started leaving a five cent piece on the fire hydrant near his apartment. Sometimes the coin would remain for days, other times it would be gone within an hour. In recent years, Jock's started leaving quarters instead of nickels. They never stay there long; Jock suspects someone's aware of his practice and keeps the hydrant under surveillance.
I worry that Jock's work may have been adversely affected by his success.
