GROTON -- Join in the Nashua River Watershed Association exploration of the science of bears -- no myths, just the facts.

What do bears do in the fall? What kinds of places do bears hibernate? What should you do if you see a bear? Why do we see bears in our yards?

Come and find answers, and ask more questions about bears, during the NRWA's Science Saturday program "Science of Bears" on Saturday, Nov. 2, 12:30-2:30 p.m. We'll meet at the NRWA River Resource Center, 592 Main St. (Route 119) in Groton.

Science Saturday will be lead by NRWA's Environmental Education Director Mary Marro. The program is open to children from all communities ages 7 to 11. Cost: $20 for NRWA members; $25 for nonmembers. For siblings who wish to attend, pay full price for the first child, half-price for the second.

Pre-registration is required. To pre-register, please contact Mary, at 978-448-0299, or email MaryM@NashuaRiverWatershed.org.
