When we get together at Darren's for a wheel bearing marathon we will take
as many pictures as we can, maybe even some movies. If you have anything
you think we should be sure to cover just let us know and we will attempt to
eliminate any confusion. If we do movies we could possible put them onto a
CD so anyone could play them on their computer.
