Minnesotans know the importance of water, but the land of 10,000 lakes can’t protect itself. Rain gardens are a creative solution to the growing need for water management. Learn where these important projects are happening here in the Twin Cities, and take home a few tips for your own home rain garden. O.W.L.S. (Outwardly, Wiser, Livelier, Seniors) is a series of one-hour programs offered for seniors interested in learning more about the natural environment. Preregistration and prepayment is required by the Friday prior to the program.
