Staying in town for spring break? Looking for something fun to do? Stop by the Montana Natural History Center for FREE activities for your kids from 10:00-11:00 a.m. during spring break week! On Thursday, March 23rd, we'll use Lewis & Clark as our inspiration, putting on our explorer hats and seeing what we can find. What can we hear? See? Smell? What can we learn when we look closely at the world around us?
