My first thought was, is it really nuts to pay money to visit a farm?  When we live on a farm?  When we have lived on farms?  My second thought was no.  The British concept of farm as attraction is brilliant.  It creates income for rural communities and allows children to roll up their sleeves and experience so many more aspects of rural life than any one family could normally enjoy.  So we timed our visit to a local farm during lambing season when we could see the spring babies and they could try their hand at bottle feeding.  The three youngest had a glorious day truly.  They wandered from pen to pasture, fed animals, dug in a massive sand pit, and jumped on the trampolines.  We lunched at their cafe and took home happily exhausted children who declared it 'best day ever.'
