I am posting both the challenge for Friday nad the one for Sunday. It is not a sport I tend to watch, but both challenges will be similar and involve NASCAR. There are no tiebreakers in either challenge and the winner of Friday's will have the same advantage in Sunday's that the Justices will have on Friday.
On Friday night, NASCAR's Truck Series is at Texas. Each tribe will draft 1 car on a first come first serve basis. Sitemail me your top 3. If you are the first in, you get your top choice. If you are second, you will get your top choice unless it is the same driver, then you get #2. The tribe with the driver that finishes the best of the 3 wins. the one that finshes last votes. Justice tribe is to send their top 4. They will get to draft a second truck after all tribes have selected their picks. Whichever of their trucks finishes better is the one that I will use. (So they can't finish both first and last).
On Saturday, the losing tribe will vote. Once the results are posted in this thread, then you can submit the same thing for Sunday's Sprint Cup race in Pocono. Once again, winner gains an advantage on the next challenge. And third place votes.
Your driver does not necessarily have to win the race, just finish better than the other 2 tribes.
