There's a lot of debate about whether deer whistles work, but when Bambi meets bumper, you can count on at least a big repair bill. If you drive through deer-infested territory, you might consider the Kritter Gitter, a stout, custom-built grill guard. Made of tubular steel and weighing about 120 pounds, the Kritter Gitter protects your truck from the impact of a deer or other large animal. The unit can drop down when you need to raise the hood, then lock back in place. Call (800) 829-7484 or e-mail critter@Southwind.net.
