Quite simple really, same rules as before...
Fill the grid so that every column, every row, and every 3x3 box contains the digits (pun intended) 1-9.
Then work out.....
S 35 AB.CDE
E 138 VW.XYZ
Where....
A = 
B = G9
C = A7
D = B8
E = C9
V = D7
W = F3
X = I4
Y = E5
Z = H8
You'll see when you get to GZ the reason we used this puzzle for this park, maybe!
Bring a picnic, or use it as a stop over to where ever else you maybe going...
Cache is in the style of 'Boom Boom Boom', 'Sixth', 'Wingaap', and 'Pump & Swing'. So therefore something between a micro and a small cache!
