Guns blazing, dealer fights Hummer slump

For Hummer dealer Jim Lynch, shrinking sales of gas-guzzling SUVs triggered an idea. He decided to add new accessories to the product arsenal at his Chesterfield, Mo., store: guns and ammo.

Mike Ryan does amazing things with the Banks Freightliner. And with Pikes Peak still half a year away, Ryan settles for practice in the Long Beach docks in "Size Matters 2." He weaves the semi in and out of boxes, does donuts in the same tight radius as a matte-black 240SX (driven by stuntman Daniel Leavitt, who ironically shares his name with a reckless driving attorney in Virgina), and dodges even larger trucks. (No Dodges, though there's the Freightliner connection.) All the elements of Ken Block's Gymkhana videos are here: the screeching electronic music, the moody industrial setting, the gratuitous slow-motion.
