Yeah, Ben!

Though I'm not directly involved in LEAD, I have been trying to follow the 
activities, and it sure seems like there's a lot of planning going on without 
much 
testing, evaluation, etc.  I thought it was just me, because I had missed 
something, 
but according to your note it sounds like it's time to move ahead!

Hopefully the LEAD meeting in Alabama will be a great place to launch these 
ideas! 
I'm sure Beth will be ready to launch her ideas too!!! :-)

Linda
