Well I quickly worked out the puzzle and armed with the hint thought I'd finish this in no time.
The first problem was getting to the garden. The way I came first convinced me it was private. I retreated and tried the footpath - and what a wonderful surprise the garden is from this direction.
The next problem was finding the cache. My experience certainly didn't fit the hint . I had three goes and failed each time. Tj convinced me to try again and today I got it.
I signed the log but its very wet. Could do with a good drying out.
