AirEd: Time to put the series to bed.
I have decided to put the series to bed rather than recycle or refresh.
Thanks for all those who found and logged the cache.
Looks like someone has been cutting the grass and clearing the area of part one up. The final nail in the coffin for the series. Given the low numbers visiting not worth replacing the field puzzle, Part 2 was still there but no way to get the coordinates.
