I just started using this, you can use clayjars watcher program after turning the .dat file to a gpx file. You can download counties at a time.

for the bmgpx program

Wow - thanks for the info... I've wanted to be able to load BMs into the GPS (and Palm) in a way easier than a few at a time... I'll have to explore this a little more..

I see the St. Louis County data is almost 9mb...

St. Louis Cty is close to 3000 benchmarks. You have a way to go to find them all Laughing

Matt, in the folder that you unzip the bmgpx.exe file make a .bat file and put this in the .bat file

@echo off
bmgpx %1 %1.gpx

Name it DATtoGPX.bat

Then all you have to do is drag and drop the .dat file onto the .exe file and it will make a .gpx file with the same name as the .dat file.
you do know how to make a bat file using wordpad right?

I have used fuzzy's BMGPX stuff before and then fed a CSV created from the GPX into Streets and Trips and narrowed down the total to ones that did not appear to be on private property, next to Interstates, or in the middle of roads.

You could also map them out using http://gpsvisualizer.com to get the same effect for free. It's just a bit harder to zoom and pan w/that.

As IBC suggested, Watcher is useful for narrowing down a radius and BMs based on info.
