Solved this one a while ago - another excellent puzzle from the =Andy Stable... I think I over-complicated the solution at first and got a bit stuck, but thankfully the co was in a generous mood and gave me a gentle nudge in the right direction.
Drove out just after lunch today, with this plus a Woking Wonders puzzle to pick up. Tried to park in Ripley but the Bonfire Night preparations meant I had to park a bit further out. Had the bike on the back of the car, and cycled off to pick up the WW cache... only to discover I must have put the coords in wrong the cache could not be there!!
Oh well, gave up on that and continued on to Andy's cache, which was a nice quick find. Log is quite damp - could do with one of those "double-can" arrangements. As I had by bike bag I didn't have any replacements... Rode back to Ripley in the late afternoon sun.
TFTC and HAF.
