Temp is probably ~60. Kids are kinda bundled up but I've been wandering around in a t-shirt all weekend.
The only thing I can say about the worker kid running along is he seems to have boundless energy. He is happy and fun and he collects discarded cups. He chats with runners and walkers. He is what one might call a character.
He's kinda chubby. Definitely not a marathon type of physique on him. But whatever - he goes back and forth, up and down. Just a real nice young fella as far as I can tell.
