GC37A2A Unknown cacheExplorer 133 Challenge

Find caches in 133 grid squares of the OS Explorer 133 map.

There is a GSAK macro that you can run to calculate your total. On the day I found the cache mine was 137.


You can find the latest count of squares for this map on my Explorer Challenge page.
