With millions of people displaced off the Gulf Coast and Louisiana by Gustav, some of them might have landed on your doorstep. If the people you are housing includes children — children who had to leave all their toys behind and may not appreciate the value of your extensive Hummel figurine collection — McWane Science Center has the cure for you. All Gulf Coast residents can enjoy McWane for free through Thursday. But don’t forget that ID. The science center is open from 9 a.m. to 5 p.m. After a few hours running around, your Hummels should be safe.
