I noticed the other day that the multipolygon relationship that you
created to define the Canada US border has a gap in it. Not sure if
was just missed, or if Paul Shipley made the hole. Paul last touched
it in July, after you created it in May.

The gap happens from the SE corner of Alberta to just south of Shaunavon, SK.

I think you created this in multiple parts, as I tried to revert back,
but that didn't bring back the missing section. I don't want to muck
things up, so I thought it best to contact you again. The section to
the east of the missing piece has also been poked at by "jaded". It
may have been due to that, or possibly another user that deleted the
multipolygon definition that defined this section of the border.

I did an undelete in the area, and come up with 3 different deleted
versions of one border or another, but nothing defining the
multipolygon similar to the ones that exist on either side.

Did we ever come up with a solution for having provincial and state
borders show up at a reasonable zoom level for the North American
Continent without "tagging for the renderers"? Canada and the USA are
massive blank spots on the map. Defining the provincial borders is
nearly useless as they can never be seen until you're zoomed in so
close that you have to go into editing mode to figure out what the
line on the screen is supposed to be.
