Say you’ve always wanted to sell cake pops out of a concession trailer, with “Stick It” plastered on the side.  Or, perhaps you’ve dreamed of pimping sausages under the moniker, “We’re All Wieners.” Here’s your chance:  Food Network is giving you a shot to start your own food truck for its third season of The Great Food Truck Race.  Get a trio of fellow foodies together who share your vision and email your name, age and photo, along with your teammates and their photos, background, and truck idea to FoodTruckRaceCasting@rrstaff.com. You never know.  Your “Fix Me a Sammich” mobile biz could get rolling sooner than you think.
