Obvious jokes that come to mind when it is learned that, of all the dens of iniquity, Los Angeles is the new home of cannabis commanders and slip-hop merchants I-45: If L.A. suddenly is recrowned the smoggiest city in America, then Houston City Council knows where to send the cleanup bill (c/o Tripp Von Slipp, Tech Ron B. and DJ Rudy Martinez 2000, a.k.a. I-45). Houston may hold the smog title for now, but keep your itchy, watery eyes on wherever I-45 calls home. Whatever you do, do not invite Slash to play your wedding reception or show him where you hide your dugout; and last, tell everyone the boys from Rap-A-Lot said, "BANG, BANG, BANG!" (Just kidding.) Though Houston -- and its "Dirty South" sound -- is currently Rap Mecca, USA, the town was apparently too narrow for I-45 and its plush but skeezy beats. L.A. simply may have been the ideal place for the trio's tunes about blunts, weed, dope and getting all smoked up.
