Howdy again!
Sure hope you are having a good time in OSP! Lots to do and see out here. I often come out here and walk around with a bag and my grabber. It is a nice way to disguise my geocaching exploits and it is good for the park as well!
This hide is just as described in the hint so bring you pen and invisibility cloak and come get this one. Watch out for creepy crawlies and muggles enjoying the park too!
