I too have been thwarted in attempts to track streams on google earth.
The vegetation on the banks obscures the water in many places and you find you have been tracking a hedge!
I live very near Tinker Brook and have strolled to it down the alottment tracks several times.
I would like to trace its origin physically but haven't the stamina.
Please will someone guide me where to look on google earth.
PS - cancel that request - found Jackhouse res - silly me
