My friend with the sand drag truck has a 4X4 quad he also uses for hunting to pull it up to the lanes (keep temps and enginehours down). When I help out, I get quad duty.

I have an old honda quad for mine, if I ever get it back together.

A friend rents a cart at MATS each year due to physical limitations. This year we went in on an old Yamaha gas cart for less than the weekend's rental. I'm currently working the body panels in auto paint class. We are going to fab up a roof/parts rack cheap too.
Looks something like this (except apart right now)
