[LVAS] Zoom Eyepiece?

Tue Mar 2 13:12:47 PST 2010

Roger,

I hope you didn't think I was making fun of you. I slip into a  
southern drawl every now and then. I grew up in LA - contrary to  
popular belief, that's Lower Alabama for the uninformed. All of mine  
and my wife's relatives still live there and you can cut their accents  
with a steak knife. Iwas just being goofy for the emphasis that it  
don't get that cold here.

Take care.

Rob
