For one of my agricultural projects, I really need reasonably accurate field boundaries for fields in the US, specifically Iowa right now but later, other similar states.
The USDA/NRSC/FSA Common Land Unit (CLU) data is exactly what I need, but apparently since 2008 it cannot be accessed by the public.
Does anyone know of a similar source, commercial or otherwise, of this type of data? I don't need much for attributes, just field boundaries that will let me aggregate analytic data within a field, accurately.

Update: The Geocommunities store has the CLU for the whole US: http://store.geocomm.com/viewproduct.phtml?catid=25&productid=2188
It lacks some of the original redacted attributes, but it's better than nothing.
