In 2006, the Dallas Museum of Natural History, the Science Place and the Dallas Children's Museum merged, forming the Museum of Nature and Science, the sort of place you could get lost in for days. For the kiddos, you can't beat the new Children's Museum. Check out the Little Urban Farm, where kids can play farmer for a day—milking a cow, gathering eggs or driving a tractor. At the Fire Department section of the museum they can practice being an EMT or a firefighter while dressing up in child-sized gear. This is one merger that really made sense.
