When we started creating the POI Megafile the only freely available collections we could find were from the
Discovery Owners website. Still today this is the primary source for these collections.
With each update I have found more companies like Pilot-Flying J, Loves Travel Stops, Camp Club USA, CAT scales, and Petro Stopping Centers to offer their databases directly.
What does this mean?
The data contained for each location is richer than it used to be
but some cases the location (lat/long) isn't as accurate as it could be.
Note: I have manually corrected locations wherever I could but as always - user beware.

Above is an example of how the Flying J information has improved for this months POI Megafile release.
