Puzzling geocaches

I attended the Coffee and Puzzles event hosted by Geocaching NSW this morning, and had a good time. As is usual at geocaching events, it was nice to put faces to names that you read in logs. The name of the event says it all really - it was designed as a forum for discussing solutions to puzzle caches in a relaxed atmosphere. The discussion covered a range of topics, and luckily I was able to solve one puzzle cache which had been bugging me for a while. Don't know how I missed the solution before - it's obvious once you know it! Hopefully there'll be some more of these events soon, and I'll certainly be attending.
