If you are after some numbers or just don't fancy a walk then this is the series for you. We want everyone to be able to find these caches so if you are struggling then check the hint or just ask.
This puzzle celebrates all the UK Megas that preceded this one. Below, in no particularly order, are aerial views of the past 8 UK Mega locations. Identify which Mega was at each location. The number for that letter is which UK Mega it was. Eg. if you identify the picture C as the location for the 9th UK Mega (which it isn't as North Wales is the 9th and its not included in this puzzle!) then C=9.
