[OSM-talk] TIGER Addressing Import

Dave - super awesome.

As I said on IRC the other week, but I'll repeat here for all - I  
think dumping the addressing for all 3,000 counties and then letting  
people import them one by one will be the best way to do it.

Another random thought - should the addressing ways be one long way  
with two nodes per block, or lots of two node ways? My immediate  
preference is for the former...?

Also - the ways will be deplaced 90 degress to the road centerline to  
push them to the edge of the road I assume - but you also need to  
'pull in' the end nodes too so they are not laying on top of the cross  
streets at each end, if you see what I mean?

Yours &c.
