.....AND NOOOOW YOU'LL FIIIIND!
The picture below is one of those "can't un-see" images. When I am traveling this route, I notice it everytime:

DISCLAIMER! To find the cash, you will need to use this sign at posted coordinates to locate the final. The sign can only be seen by traveling northbound. DO NOT STOP ON ROUTE 74! I listed the picture for you to note the discrepancy beforehand. You will need to drive passed posted coordinates to collect the information to fill in 'X' and 'Y'. Reaching posted coordinates is your cue to utilize your right turn signal. After noticing the sign, you will be turning right onto Rt 425 as the sign indicates. After turning right on Furance Rd, continue north and take the second right on to E Posey Rd.
GEOCASH! One of these words is not correct. The direction with the incorrect word is listed either as X or Y. Use this info to determine coordinates. You will find the cash at:
N 39 50.(X ? Y x 114)
W 76 22.(X ? Y x 193)
Not very far from the closest parking, the cash is on State Game Lands
