This should be a short 2 stage multi. Stage two is a short drive away, or could be a nice little stroll. You will need to do some simple math to obtain the coordinates for Stage 2.
At stage 1 is a warning sign in the park. On the bottom of the sign is a 10-digit phone number. Let those numbers be (ABC)-DEF-GHIJ.
To find stage 2, solve -
N 033 ED.BB(D-C)'
W 096 I(H+I).(G+G)(F-A)H
