[GreenKeys] DOVETRON ARRIVAL

Wed, 4 Jun 2003 16:45:03 -0700

Hello DOVETRON FANS,
The Dovetrons arrived today via ROADWAY and were off-loaded at 12:08 PDST at
the "ONE & ONLY SURPLUS STORE left in Washington State. Fortunately, for us
George is working  swings, called through his ESP vision, and came down to
unpack, do a preliminary inspection and help make space to "TEMPORARILY"
store them until they are checked out. We still need to requisition
standardized boxes and start the homeward trip to those parties who have
paid.  George, will follow-up with a informal "FORMALIZED" report to the
group. He took a sampling of the Dovetrons so he can do a anxiously awaited
eval. All the best.
73,
