I can't remember where you said you were but the Lubbock Bike Club does a Big Bend Ride every February. They were the ones that ended up being our unexpected SAG in May, they were doing an annual Fort Davis weekend. If DH could get off this Memorial Day I would jump to go out and do it again, I really love that area for a visit. I wonder if they have a contact on their site who might give you some tips? You should have a great time but won't it be cold?
