Driver changes

Muddy came back in with high temps. We were very low on coolant, so refilled him and sent him out. Everyone of course very worried about where the water went as there was no visible leak nor anywhere that we could see evidence of a leak. 

So we filled him up and sent him back out. 

20 minutes later, we cycled both cars through the pits and changed drivers. 

Queen is out in the D and Lugnut is out in the Z. 

We were a little low on water, and the thinking was the radiator cap. So we refilled, changed the cap and send Lugnut out.
