The final cache can be found at 52 56.abc -1 20.abd

Note added 1 week after going live: I have already had to attend to 4 of the 19 caches on this series. Please replace caches as you find them and feel free to email or leave a note if you find a damaged cache. It is clearly too much for some of our caching community to replace things as found, so intent are they on moving on to the next smiley.
