BC is larger than most countries… you really should have a region level in the heirarchy.
Lists came into being around the time I was doing my entries as I recall…and weren’t integrated quite as nicely as now so that does produce a way to at least get them in.
Just so you know the rational, for the one example of a coastal mountain highway, it encompasses North Vancouver, West Vancouver, Horse Shoe Bay, Sunset Beach, Lions Bay, Porteau Cove, Britannia Beach, Shannon Falls, Squamish, Garibaldi, Brandywine Falls, Whistler, Pemberton, Mount Currie, Darcy
Several of these fit into no CITY or municipality … stating they are part of BC doesn’t come close to saying where they are—having regions of BC does.
At any rate, good luck with your continued work.
