I had the delightful experience of insistent knocking on my door this morning at 6:35. It was Arnold & Kathy of Houston representing USADA. Which was fine although it took up some time this morning. What was a bother was that I didn't even produce a valid sample because I was too hydrated and my specific gravity was too low. Drats. If USADA is going to make me pee into bottles and double check that said bottles haven't been tampered with and have the correct ID number on them and sign my name five times I at least want to be able to add a negative test result to the list.
