seventytwo: It looks like this cache has been removed for whatever reason. Looking at the logs it probably happened around the end of March 2021 (I'm counting the one find in that time as spurious). The hide area has changed a bit in the 20 years it was placed so I couldn't even find the original tree with 100% confidence myself.
It's a shame, but it's done well to be there as long as it has, there weren't anywhere near as many caches when it was placed. I'm not planning to replace it with a new one.
So, end of an era maybe, I want to thank everyone who has visited it over the years.
Happy geocaching.
David.
