Well, I knew a chap who used to garden for a fellow whose aunt was married (her first marriage) to the third son of the best friend of the uncle (by marriage) of the chap who taught Geography in the Texas high school nearest to the one attended by Lance Armstrong.
He said (and this is inside information, so treat it as such) that Lance just wasn't the kind of kid who'd get mixed up in all that ugly old drug stuff.
He knew this because he'd been assured of it by someone as close to the family as he was himself.
Now that I've revealed that (probable) truth, there is no way this thread will reach 100 pages.
Please all pack up your prejudices, clear up the mess you've made and go home!
I hope this has helped.
