I was out driving yesterday, a way that I don't usually go, and saw a barn/farm for rent. Since I know there are always posts on here about people looking for a barn, I thought I'd post this. It's called Schuster's Playtime Farm and is near Cambridge (southeast of Madison on Hwy 18). They have a link here:
