YESS! Curb ball was fuckin sweet!!! Plus all you needed was a ball, 1 friend and a curb. Haha
But I'd have to say that things like tag and the other mentionable are still around. There are a bunch of kids in my neighborhood and now that it's warmer out I see the basketball hoops going up kids on bikes ,playing football in the streets and yes, even curb ball! On weekends I hear kids out till about 9-10pm.
So to answer the question, I don’t think they’ve gone anywhere, sure things have changed but I think we all have just grown up.
