[Tagging] Another multipolygon question

[Kevin Kenny]

I'm somewhat familiar with a couple of places that Alaska Dave has mapped,
and they're the sort of places where the shoreline must be mapped from
winter, 'leaves down' aerials, because otherwise the shoreline is obscured
by overhanging trees and matted aquatic vegetation.
