The ancient way that is Mount Pleasant has its roots in the Rosedale Ravine. Jarvis street somehow is transformed, somewhere when Jarvis runs under Bloor. Ask around, nobody knows where, exactly, Jarvis turns into Mount Pleasant. They just shrug, ignorant of the greater mystery. Nobody knows where Aylmer turns into Rosedale Valley road, either. There is a park down in the ravine. It has park benches. But you never see people down there. Only cars zooming through, on their secret shortcuts.
