One of our team members grew up on this park - no, really, his family took him there day and night and so it continued with his friends playing sport or having an ice cream, to this day he still wanders off to the area to see his childhood friends. So this park is a sentimental park and what do you do to a sentimental area?
you put a cache in it
Bring your own pen and happy hunting :)
PS Please please replace the cache as you found it to avoid it being muggled (High muggle area)
