Pilot list
here.

Almost all the pilots who have registered have also paid their entry fees. We
have contacted all the pilots who haven't paid their fees and who have
registered to let them know that they will go on a waiting list after July 22nd
if they haven't paid their fees. We have also contacted other pilots who have
stated that they are likely coming to the 2013 US Nationals that they need to
register and pay their fees by the 22nd or they will also be put on a waiting
list.

A full refund of your entry fee is available at any time.

The cost of towing us all up is estimated to be between $14,200 and $16,000
depending on how many pilots have registered. The estimated cost to pilots
varies between $400 to almost $500 per pilot, with the number of pilots per tug
varying between 10 and 12. The towing fees will be due when you come to Big
Spring.
