following myself up, which some people tell me is bad form...<br>
<br>
my work on track documentation suggests a need for more than<br>
just start_date and end_date; tracks drift in and out of operation<br>
over time and end up with multiple start/stop dates. on top of<br>
that, there are tracks that were clay then paved or paved then<br>
clay, and in one supremely novel case, there is an inactive<br>
track not far from where i live that had pavement in the corners<br>
and clay on the straights for its first year of operation (not
enough<br>
money to pay for pavement all the way around.)<br>
<br>
right now i don't really know how to model something like that<br>
in OSM terms.<span class="HOEnZb"><font color="#888888"><br>
