6 Hours Early?

Brian is supposed to leave tomorrow for a week long trip. His flight is at 4 am and they want them there tonight at 10 pm. REALLY?? Brian could drive to the destination in 6 hours! Why on earth would they want them there 6 hours early?!
I am praying continually for him! He has been SO sick and I am afraid the exercise will be hard on him! They can work him up to 16 hours a day! This will NOT help him get over the "Crud" he has.
Have a safe trip my love!
