Nothing like a farm on the layout; the two go together. We have a friend in Vermont who has a family dairy farm and still has a train running along their fields.
On our prior holiday layout we had a small triangle of empty space coming off a curve and filled it with a modest gentleman's farm. It had a small footprint but it was always a favorite scene. The bull and milking maiden are Arttista, the corn stalks and hay bales JTT Scenery, and the cows Woodland Scenics. Somewhere in the corn stalks is a scarecrow from Scenery Express. At one time Hobby Lobby was your friend for scenery items as they allowed you to use a 40% off 1 item each time you came in the store, but alas, no more.
When we get another layout up (if?), a farm is in the plans
