This delighted me!
Wait. This is a real place?!!
Fun, eh? I love this-
"Because the Site of Reversible Destiny-Yoro Park has many steep slopes, we advise that you wear rubber-heeled shoes."
This is my favorite:
"Should an unexpected event occur, freeze in place for as long as you see fit. Then adopt a more suitable (for being more thought out) position for an additional twenty seconds or so."
I feel like that's advice applicable to life in general.
And the bit about rubber heeled shoes. Life's hard enough without having to moil through in unsuitable footwear.
Also, reaching the point where practicality is a major factor in footwear choice should be considered a life milestone on par with getting a driver's license or voting or being able to buy one's own booze.
