A bit of history in the bustling heart of town, which should then lead you on an easy stroll through an area of peace & quiet & on to GZ & tranquility
(I hope)
You'll need your own scribble-stick to sign the log and to jot down notes to solve the coordinates!
* I also highly recommend visiting GZ between 10AM-4PM*
If your timing is lucky, on certain days you will have the added bonus of peaceful music, courtesy of a lovely Rose 
Stage 1
Go to the start coords,find the plaque and pathway, solve the coords to stage 2.

take a seat, what you need to complete the final coords will be in view.
S35 43.JKI
E174 1L.MLN
I= Number of letter on red brick building Well, the old building is long gone, making way for new development! It Was the old RSA building, so I=3
J= number of pou you can see
K= digits of pharmacy address added together
L= number of pou + number of letters on red brick building
M= street sign name, number of letters minus 1gosh, this sign is too popular & has gone missing again! Can you guess it's name?
so... M=9
N= using pharmacy address, subtract 1st digit from last
