Well what had to be done, was done at the time.
Its kind of like a 'to do list' for the young'ns at Winter time, I mean the season comes once a year, so I guess some kids look forward to these activities.
Try educating the young about safety, if they are in a big group, the blame gets shared and its worthwhile to risk a whoopass if you got caught that is. Which brings me onto the next bit, some kids throw snowballs at Van, Cars but not Busses because they want to provoke Driver Rage and get a Chase.
The buzz would come from knowing the driver would not know where the heck your hiding, the drivers would have a big disadvantage since its your neighborhood your playground, your rules "system".
My 2 pennies coming from someone who part took in these childish events, there were no Xbox that time, I'm sure there were Scalextric though.
P.s it was just snow, I despise people who use Bricks, Rocks and oh yh Household Appliances.
