Thanks to everyone for the replies. Some nice links there! Matakishi I think I will go with the cornfield in your link. The ploughed fields look good too!
In the past I would have made my own, but now I'm back in college part time, and holding down a full time job, its hard enough to find time to fit in painting my figures let alone making scenery!
Love the pic by the way Matakishi, I take it those buildings are scratch built? They look stunning.
