That's good, the sooner, the better. I booked my original 10 days when I left there in Dec and added another week a month ago. My gut tells me that if things clear up by the end of summer, early fall, there'll be a rush to book and that Oct and Nov will be busier than usual (especially at White Sands, with it's more affordable costs) since alot of people missed out on their late winter/early spring trips this year.
Go Bills!
