Men with a garter should have been smarter
Than to mix drink with their vulcanic activities.
You would be wise to look for the prize
By taking up a child’s proclivities.
Clearly a reference to last year's "incident" involving a few Vulcans and the waitstaff at Alary's bar. Alary's used to have a website with pictures of their waitresses in various stages of near-undress, but it's been disabled since shortly after the incident. As an aside, you can still go to google and do an image search for "Alary's" and turn up some, shall we say, interesting photos. That short piece of dubious history aside, all this clue really tells us is that there probably is a playground or something similar. Could be a way to weed out parks that don't have a playground, or could be a clue as to which part of the park. I'm not really sure just yet.
