The Cache
The cache is hidden in Shanganagh Park, a lovely park in south county Dublin, made up of two large green areas separated by the DART line and stretching right down to the coast. There is a popular children's playground at the main entrance to the park.
The cache is a small camouflaged lock & lock container. I have been generous with the clue, as tree cover may hinder your search.

Extra bonus linguistics joke....
A linguistics professor was giving a lecture. "In English", he says, "a double negative forms a positive. However, in some languages, such as Russian, a double negative remains a negative. But there isn't a single language, not one, in which a double positive can express a negative."
A voice from the back of the room piped up, "Yeah, right."
