Dear John, I love it! Do the records in your database have any connection at all to the odometer readings? (Probably not.) So, you need a way to calculate travel distances between physical addresses. I t would seem that a mapping program of some sort would provide the solution - just as Google Maps and MapQuest tell you how far it is from home to the VA hospital in Ann Arbor, for instance. It's not yet clear to me how to get your addresses out of the database and into the mapping program, but, there's got to be a way. Thanks for a great puzzle - don't know how much help I'm going to be in its solution, but I'm going to give it a solid effort.
