Roger: On a single tour.. Hmm.. Probably more than five. Cause when we first started, we had a really old van. It was a '79 Chevy. It was like the kind of thing where we'd pull over and get gas and it'd need two quarts of oil every time. That kind of thing. It'd break down pretty frequently. We have bad luck with vans. It's some sort of curse. But, then we got another one after that and that one was good to us for many years.
