RE: Chaining with a very large file

I would assume that Doug has all of the mileages from another source. 

Probably can't use lat/lon as he probably needs the industry standard 
mileage.  Lat/lon would give you nautical miles.

I assume by "road mileage" you mean actual mileage if driven, and you're
not missing the obvious option of computing the distance between the
zips based on lat/long.

Also, I doubt you know all the mileages between each zip (hence dist
isn't required), but do you even know a high percentage? Why not only
store records where you know the distance? Might make the file much
smaller.
