Synchronized parking,memorial park?

"Why are all these folks out here driving like they own the road, purposely causing chaos? What's the deal? What's the message behind revving those no-muffler-having-cars through Memorial Park? Spill the beans, maybe there's some hidden wisdom I'm missing. Is it just because gas is cheap, or is there some deeper meaning I'm not getting? Or is it just a case of having nothing better to do?" Is there at least somewhere y’all organize and post when and where your gonna be pulling these stunts so I know to avoid the area ahead of time? Be safe, drive kindly and take care
