ebone, the event center location is shown on the google map on the
hospitalities page. It's a bit hidden. Sorry about that - I'll fix that on the website this weekend.
Pink Socks, we don't have that information but based on last year it will probably be a 3 hour start window likely starting at 9:00. We're leaving enough time so we can have mostly separate elite races to build on the spectator experience seen at the 2012 North Americans.
It's about a 45 minute drive from the Airport to the Hidden Meadows Farm (the middle and long arena) so we should be able to fit you in at the end of the start window.
