Trial lawyers have taken a lot of the fun out of being a kid. Thanks to lawsuits or threats of such, teeter-totters, merry-go-rounds, jungle gyms and straight metal slides have long ago disappeared from parks. And diving boards have mostly disappeared from swimming pools.
Don’t forget ball pits from play-places in fast food restaurants; in fact, just include entire playplaces.
(Chik-Fil-A, thankfully, has not succumbed to lawyer pressure to remove their playplaces. This is likely because liberals do not patronize Chik-Fil-A in the first place.)
