[Az-Geocaching] Changing of the Garmin III+ way point max

There is a file, az_caches.mps, that has all of the caches for the state of
AZ. When there were 500 or less caches I was able to load them all down to
my Garmin III+. But now the number is close to 900 and the file does not
fit. I do not know who created the file or if there is anyone else that is
having the problem. Does anyone know who created the file? Is there a
chance that it could be broken up into smaller parts? Like a north part
that starts from Prescott and goes north, one that goes west from Phoenix
including Phoenix and then one that covers the east part of the state.

Thanks
