<div>If anyone has any advice on tagging please let me know.
Just this simple case has pointed out many interesting nuances
about parts of things that change over time & how that
impacts how that thing should be tagged. Or, if 1 part of a
state's border changes, how do we track that? Or, should we be
citing sources for almost every tag? Vector tiles, anyone?</div>

for that matter, while i've been working on the 1895 race in
chicago,<br>
i've been looking at the change in the Chicago shoreline; it's very<br>
different back then (there's been a lot of fill out into the lake
over<br>
the years.) what do we do about shorelines over time? OSM modeling<br>
assumptions don't offer a straightforward solution.<span><font color="#888888"><br>
