Saturday, May 21 from 9:00 am to 12:00 pm As spring rains are falling and flower buds begin emerging, it is time to join in the spring cleaning at GRNA! Trail grooming, garden weeding, and window shining are a few of the many tasks for freshening up our grounds and Center in preparation for summer. No experience is necessary, just a pair of gloves, a "spring" in your step, and an open spirit. Pre-registration is encouraged.
