Park gates may be closed during the winter and if so you'll need to proceed on foot. The outer loop of the park is 3/4 mile all the way around. Using either method should require a walk of less than 1 mile. Traditional Method All numbers can be obtained within the park on the paved roads. I'll admit to requiring what may seem to be an annoying amount of math because I'd rather have seekers use the QR Code method. Feel free to shake your fist at me 
The cache you seek can be found N 40 14.TSM W 78 49.RQP
AB= The maximum age for a child to use the playground.
CDE=Ordinance number making it unlawful for your dog to defecate on public property.
FG=Speed limit within the park.
HJK=Ordinance number making it unlawful to allow your dog to run at large.
L=HJK+HJK
M=L-CDE
N=AB-FG
P=N+1
Q=M+P
R=N+N
S=N+N+N
T=Q-N
Hope you don't hate me!!!
QR Code Method The first QR code you seek is very near the posted coordinates. There are 4 QR codes to find that will lead you to the cache. None of the QR codes are in or near the fenced in swimming area. Simply scan the QR code and watch/listen to the instructions. Have fun!
