I'm hoping this doesn't last very long into summer, but some type of grass or weed around the playground in the park where I take my son often has some type of "sticker" on it. I think it's the seed heads or something that have tiny barbs and omg they hurt BAD like a bunch of needles jabbing my feet. After I get off that area I have to pick the stickers out of my feet. These prickly things just popped up in the last couple of weeks so I'm hoping they go away soon.
A city playground hazard in NYC is the black mats placed at the foot of sliding ponds, swings and climbing structures. They get extremely hot and have burned the feet of a number of children. I've seen news reports on these over the past two years. Some children have suffered deep burns and pain. The city installed these to prevent head injuries and break falls. Their answer to the heat issue is to make sure children wear shoes while playing on these.
Of course, when it's that hot kids are likely in shorts and t-shirts too. So when kids take a fall on them, they won't bruise their knees or elbows but burn them instead. Good thinking of the city.
Here, we have those all year round. You will too, unless it gets super wet or something, and they rot.... The plant would be extinct if they didn't last until the next growing season.....
It sounds like your describing sand spurs and they're usually in the south of the U.S. They do eventually go away, but they're miserable when they're around.
Well most of the park has been mowed recently so most of those stickers are gone I think. Thank goodness.
