To encourage learning, the Authority offers public tours of our facility by reservation Monday through Friday, between 9:00 a.m. and 3:00 p.m.

We welcome both children (10 or older) and adults on our tours. To ensure school groups get the best and most informative experience we ask that you include your school name, classroom size and grade and any special areas of interest when your request your tour.
