This cache is located in Mary Brogan Skate Park near the entrance, and also near the entrance to Pinewood Elementary School.
Needless to say, there are Muggles galore, especially during school hours, so stealth yourself accordingly!
This one's a bit trickier to re-hide, so please use care to make sure it's both hidden and accessible.

Congrats to legoland2010 on FTF!
Update: Given the amount of trouble people seem to be having with this one, I'm changing the difficulty rating from 2 to 3. I will still recommend that you find at least one of the other Little Darlings in this series first to help you with this one.
