Simple -- there's been a lot going on here on Westwood this Summer. New ex-con's have moved into the 'hood. Of course, they have attracted an interesting assortment of cops, dog catchers, habitual offenders, ambulances, fire trucks, etc.
It began around Bele Chere and has been active ever since. This is an easy way to remember who/what/why/when. And there's been plenty of it.
So enjoy the mayhem! I'll try to post the news as it happens (usually in the 10pm to 4am 'Drunken Hours of the Morning')
