I'm convinced there is no Charger team. I think these kids, some of whom are very young, are being forced to beg on the streets. I don't know where their parents are, but there are minders standing close by watching their every movement.
It appears to me that these children are there under duress and that someone should be investigating this scam/criminal activity.

Are those the people in the neon shirts at stoplights?

How many $1 chocolate bars do you have to sell to subsidize a track team? It's not an expensive sport, at least if I'm correct in assuming that they use a facility that's been paid for.

Uniforms, sneakers, socks...what am I missing? How frequently does a shot put or discus need to be replaced?

Awhile ago, there were a bunch of kids doing door-to-door solicitation out here in Hopkinton. My wife is a real softy, and after talking to one of them thru our doorway, she invited him inside. We talked for quite awhile, trying to figure out what the charity was for, and never really got a decent answer. The kid seemed like a really nice kid, but something didn't feel right. We finally said thanks but no thanks, and led him to the door.
After he left, we talked about it, and figured that he was just one of a team, working for some guy who just dropped them off in neighborhoods. We kind of felt sorry for the kid. He didn't seem very street-smart and was being taken advantage of.
