I hesitate to rate another person’s cache but GC28Q1K was well up there and is one of my all time favourite caches. The one “Found it” smiley was worth more than the 105 I earned on my highest find day.
It’s all down to one’s individual ability. GC28Q1K took a fair time to solve all the seperate puzzle mathmatics and then several trips to the far apart stages all needing special equipment which needed transporting to the stages over not too easy a terrain and I’m on my own.
May I therefore, respectfully ask the Plymbridge Runner how many of the “easy” puzzles they solved and why they didn’t find the final cache.
