[Imports-us] Denver Buildings Import Discussion

Wed Jan 25 16:19:42 UTC 2017

Russ, Chad,

Sorry if I jumped the gun.  I don't think I will be able to make it
tonight, but if you provide a link to the original data I could do some
work, provide some - hopefully helpful - feedback, and with your OK, help
flush out the wiki page.

Again, it is great to see this moving forward!

Mike
