Re: Who wants to ride??
I've seen a contraption that has wheels and a tongue with a long bar that has magnets mounted to it that is pulled behind a vehicle to pick up nails, screws etc. I don't know of any that could be mounted and pushed so there is the possibility still of the tow vehicle getting a flat. We had one at work and I've seen them at rental places but I don't know what it would run to rent one. I also don't know if it would be strong enough to pick up a spike or not.
