The latest cache is bringing people to the park who either never knew of its existence or hadn't visited for years (which is exactly why so may people love this hi-tech form of treasure hunting).
Here's a taste of some of the comments left on the geocaching website:
nice cache and great view. thanks.
This used to be a swing park where i played many years ago. Nice to revisit
nice wee cache
A pleasant hidden park, nice murals
Prestonpans is just full of murals and was nice to see some more that we never knew was here
a great little park we never knew was there..
seems like a nice place to have a wee picnic lunch
What are you waiting for??
