Due to a leak on a bellows between cryomodules 1L09 and 1L10 beam into 
the NL is delayed by at least another ten days.  It follows that five 
pass setup will, in my estimate, finish no earlier than Thanksgiving. 
It would be very helpful if the Hall C polarimeters could participate in 
the spin dance needed to optimize Wien angle and perhaps adjust 
accelerator momentum to maximize polarization to B and C.  Would this be 
possible Thanksgiving weekend?
