I'm with you, Dan, not enough to go on, but maybe Amelanchier spp.? Leaf looks like mine.

You think perhaps Serviceberry? Related to Crabapple, the internet says. I'll try to snap a pic of the berries and tree when I get a chance.

Ok, pictures of the tree and berries:

It's an ornamental crab apple.

Excellent. Couldn't imagine they'd load up a playground with thousands of poisonous berries, but better safe to know.

Thank you very much!
