I just wanted to give you a heads up on an incoming email. I spent the day yesterday with the Aethon leadership. Albert Huddleston, the head of Aethon, was hoping to get on Chris' schedule at some point for a brief meeting. I suggested he should do that through you so have shared your email address with him. Chris knows him well - I believe they chatted regularly prior to the move to DC. Take ca re, and do stop by the office for a visit when you're back in town. We miss you! Ron Ron Gusek Sierra Club v.
