I got them from this site:
This is the Nebraska sustainable ag site. My family is very active with this organization. They always need members so if you are interested in organic or sustainably grown food this is the group you want to join. There is a List serve where you can talk directly to producers (and probably find closer producers yourself), but i admit i do not know much about it (Dh is on it, not me) but you do need to be a member to get on it.
ETA: Ostry Family Farm is one i actually know, they are north of Seward, but it looks like they regularly deliver to Lincoln.
