Forgotten Picnic Ground Traditional Cache

On the edge of the Goulburn Industrial Estate is this abandoned picnic area. It has become a favourite excersise place for my geodogs who sometimes try in vain to catch a rabbit here.

 I think it's a beautiful spot, I especially like the view over the river to the cliffs and the big old gum trees. Sometimes you might see a train go past. I like to imagine what it would have been like when the picnic area was in use. Also if anyone has any idea what the small brick structure is, I am interested in finding out. I would suggest parking in the designated carpark at the higher end of the park and making the short stroll to GZ. You are looking for a small glass spice jar. No room for swaps and please bring your own pen.
