I attended RSMAS and lived in Miami for 15 years.  How's it going?
You guys still across Dixie from UM?

Timely question.  I've enclosed a reply to Gregory Grosshans (also of 
NOAA) on just this issue that I answered just this morning.  Take it 
as applying 100% to your situation, too.

Basically, I need and would like some help to solve this problem.

Regards,
Steve Emmerson
