The Treadway's

I liked that video Emily, the Today Show had it on there this morning. I don't recall the boys ever having any conversations like that when they were babies, however, it sounds quite familiar now a days LOL!! :P They would coo to each other at times though. We watched "Coal". It was very interesting. A few things seemed familiar to me probably from David's book. Rita, what did Blain think about it? Mark was wondering how often the tips had to be replaced on the 'continuous miner'?
