Bread-Bakers v109.n011.7

I mill my own bread flour, and have been using Golden 86 (AKA Prairie 
Gold) wheat berries.  I live in the Baltimore area, and having these 
shipped form the source, Wheat Montana, is prohibitively 
expensive.  Shipping costs by UPS ground are about 3 times the cost 
of the wheat.  I am looking for a local source. Does anyone know of a 
local supplier, co-op or buying group in the central Maryland or DC area?
