If there is a park for 'children and their guardians' only, where is the park for 'single adults only'? I'm only half joking, but seriously what if a single adult wants to go play on a swing set to regain his youth - isn't he being discriminated against?

I'll bet $100 that none of the people they tried to kick out were clean cut businessmen wearing a suit and tie.
