We went to a local Dairy supplier...we get out milk delivered round these parts!
They had an open petting farm for kids to see and feed animals with.
In Colorado you can go to White Fence Farms, or Karl's Dairy like we did. Longmont Dairy doesn't do tours anymore otherwise we would have gone there since that is who delivers our milk.
the best thing about this little trip is that it was FREE! Contact your local Dairys or
Farms and see if you can tour today!
