Geocaching clue in Gregg shorthand?

I am in involved in a treasure hunting game called geocaching.  Often the clues to the treasure are coded in devious ways.  I've found a clue which I believe is written in shorthand.  I've attached a picture of the clue.  The answer should be two rows of numbers.

I'm hoping that someone in your group can decipher this clue for me.  Please e-mail me directly.
Thank you in advance....
