Mr Dunn-Hill has been trying for a few years to get a small fenced, but unused, area near the overpass (see the overpass pic elsewhere in my gallery) in my neighbourhood to be converted into a dog park. Meanwhile, he takes his own Staffordshire out on Sundays for a good afternoon of jumping around.
Thanks guys; I'm calling him this week so that he can have a copy. The encounter was a chance one, and in the most unlikely of places, which was very nice.
