Hi Bob, 
fine with us. As soon as at JLab, we will do our best to get the RICH 
ready to go at the earliest weather copnvenience. The effort to 
uncable the RICH and prepare the crates (except interlock that will 
move together with RICH) is in the hand of Electronics Group: 
Ben is in cc. 
Thanks, Marco.
