winaed,

Yes, I thought about developing an application in vb to find the mathematical center of group also(a euclidean algorithm would work), but thought that there may be a built-in function or add-on for such a thing. Using MapPoint to find a location(such as a resturant) near the mathematical center would be the ultimate solution. What I'm looking to do is identify clusters of contacts(say within 15mins of each other) among those in each region and then find a central meeting point for those contacts. To be able to highlight those groupings and have MapPoint find the meeting point(or close approximation) would be the goal. Thanks for your help.
