Dave, you can show up and leave whatever time you like. Most likely I won't be heading back until later that evening (9 PM +/-). It's pretty simple to get to the track as it's intertstate except for about 10 miles and I'll have maps.
I was actually thinking if some of the Minnesota guys don't want waste 4+ hours drive time they could meet us at the track on Saturday and then come back to Des Moines that night. I do know there is a bunch of guys from several clubs in the twin cities doing a caravan that day to the track so I can set anyone that wants up with that info too.
Rick
