Looks like there is a now a newly planted cache in Humboldt park. I could be missing something, but there seems to be no clues as to how to find it... other than the fact that it's in the park. Very helpful. Seriously is there some hidden puzzle here or did they just forget to post the puzzle... Ahhh... this is driving me crazy.
Carry on my wayward son, there'll be peace when you are done.
