THIS TRIP IS FULL.  Join us for a morning at and around Riley’s Lock where we will first spend some time scanning the river for waterfowl. After that, we’ll head upstream on the towpath checking the turning basin for any elusive waterfowl and then continue on looking for winter woodland birds. Meet at 8:30 a.m., and bring a scope if you have one. Limit: 8. LEADER: Scott Young at [email protected]. Dave Roberts will co-lead.
