You are looking for a small magnetic cache. There is only enough room for the log.
There is ample parking at the location, as long as you don't stay long.
This is number 4 in the Bury cut through series. It is located at the start of a walk through from Newmarket Road through to Westley Road.
Congratulations to Disa urq for being Fisrt To Find on 4/1/20
