Welcome to the All Roads Leave Ballarat series. This is part of a series of multi caches placed on 20 of the roads that leave Ballarat.
This is the Ballarat-Carngham Road, Highway/Road number C296. It leaves Ballarat through the suburbs of Alfredton and Winter Valley, passes through Carngham before taking you to Beaufort.
At the posted co-ords you will see a sign with an 8 digit phone number. Using the first 4 numbers as ABCD, you can calculate GZ as follows:
S37 33. (C+D) B (A+1)
E143 44. 0 (A+B) (D-1)
Checksums: South 31 East 25
There is plenty of room to pull off the road at both the posted co-ords and GZ.
