Please don't import these without verifying against your own local 
knowledge or other sources. Experience is that they are poorly 
geo-referenced and/or have other problems. For example, in this file, the 
only one in my area is wrong:

13095 Jamboree Road,US,CA,Tustin,92782,33747885,-117767370 is actually 
about 1.6 *miles* southwest of that point.

Is it possible that there is something wrong with MapQuest's process that 
causes users to misplace things so much?
