While hunting for grrbears cache nearby, my muggle daughter decided to check out the entire park and scout locations to hide new caches. This was her favorite place so it is dedicated to her (in hopes that I can hook her and gain another goeocaching partner-wink!).
This place is crawling with gardeners all week - Friday morning to early afternoon, it is free of almost all muggles. I have seen this park open as late as 2pm so don't think it ever closes but cannot be certain.
Please make sure the rough covering is replaced as found when you leave.
