  I've been going through the data deeper this morning, and validating 
with imagery. Many grain silos are mi-identified as buildings, and the 
usual bug in Bing footprints, all converted to squares. :-( Luckily 
they're often in groups, and usually near farms with lots of other 
buildings, but I'll have to be careful. And there's also some great 
Salvador Dali "footprints" in farmers fields. Changes in topography are 
also getting misidentified, but easy to find. I'm getting some 
interesting screenshots for a future conference presentation. :-)

  Nice catch ! I'm not sure why that building got skipped, I'll have to 
check my software. There could be others. I may import what is in the 
current results since I already started cleaning it up, then make 
another pass as a followup to get anything missed. I'll make sure the 
bug is fixed before doing any other counties. I've been mostly focused 
on making sure I wouldn't be adding any duplicates.

   This part of Colorado is definitely a desert of OSM data...
