I heard back from Scott, and the NW Mustang group appears to be settling for hotel rooms rather than opt for renting a second house. I am posting a link for those who want to attend but need to arrange hotel rooms. An alternative would be if you choose to take on the task of renting a house on your own, and find people to share it with you here. I can make the contact info available if there is any interest. We are two away from having 20 cars for Vegas. We need 20 paid MCA entries by 12/31/2013 for the preferred parking.
