I remember you by the bridge. I was in the 4/5. That was tough for anyone's first race. The course was challenging to say the least. Everyone focuses on the dirt, but the hill finish and the headwinds on the highway portion were brutal too. I thought the old Tunis course last year was easier. Anyway, the Aggies always put on a great event and everyone should give it a try. Just know what you are getting into. I ran 23c Specialized Armadillos with Slime tubes at about 120psi and I never flatted.

To answer your original question... you did the right thing. It was clearly advertised as a "wheels in, wheels out" event. You were under no obligation to provide any assistance. That was cool that you gave up a couple tubes though.
