I grew up a half-block from waterfront. The minor streets in my neighbourhood were all paved with oyster shells. When they repaved, the place smelled at high tide the way it smelled at low tide. For a few weeks, then the stench went back to its twice-daily miasma.
I don’t remember the shells ever doing bad tire damage. Boy, did I ever get sliced up on them a few times by falling off a bicycle.
