I took the kids to Drumlin Farm in Lexington with a library pass, so it was only a dollar or two for the day. A friend recommended it to me and it really was perfect for them. We just wandered around the working farm and looked at chickens and horses and sheep and cows. Anna loved weighing and sorting the pretend eggs. We went back twice. The kids also liked watching the sleeping piglets. They were both very quiet and for the rest of the day Anna would say, "Shhh Mama! The piggies are sleeping!"
