The TV show Blockbusters originally appeared on the TV in America. It was not successful, however in the UK it was a great success mainly due to the host host Bob Holness (1928–2012). He had a cult following amongst students, with catchphrases that included "Can I have a 'P' please, Bob?".
So to the cache!
To claim the cache and sign the log you must have found 5 Countries that are joined together in a line or are touching. Some of my qualifying caches are demonstrated in the graphic below expertly put together by Christopher.

In your log please either:
1. Enable your maps on your cache page and list the Countries you are claiming in your log.
2. In your log list one cache from the Countries you are claiming including cache name, GC code and when you found it.
Cachers claiming the cache and not demonstrating compliance may have their log deleted.
Good luck!
