M2M (Marston to Marston) was placed on my daily exercise walks during lockdown.
Hopefully, this series of 15 caches and bonus will entertain you when our world gets back to normality.
Each bonus number can be found twice in the series, to enable it to be done in either direction. The values A, B, C, D, E and F add up to 20, so if you have one DNF you should still be able to find the bonus.
