What galls me about this series is that they're tooling around in crappy high mileaqe vehicles like that lousy motor home and old Chevy farm trucks from the '60s -- yet they've passed up perfectly good Stryker/LAV-25 AFVs and HMMWVs just sitting around.
How about this. Create a large wire excercise wheel like in a gerbil cage, and attach it to your trailer hitch. When you capture zombies, lock them in the gerbil wheel. As long at you sit in the driver's seat, they will try to come get you, pushing the gerbil wheel and pushing the car forward. Its a zombie powered car.
Don’t send that idea to the White House, please.
