Here are two events to inspire you and allow you to learn from professional photographers: Sat. 9/6 - Lonna Kelly will lead a photo walk to the Clough Preserve on Farm-to-Market Rd. in Patterson. Stroll a wooded path with ferns and mosses bordering a wetland which opens out onto a beautiful pond. This is an easy and very interesting hike, and the autumn colors ought to be lovely. Any kind of camera will do! Please call to register and get details on when and where we will meet for this photo ramble. This will be followed up with a program given by Lori Adams on Preparing Your Photos for Competition at the Patterson Library on Thursday, September 11 at 7 PM. Call 845-878-9248 or 845-878-7740.

The Great Swamp --nestled in the Harlem Valley and covering over 6,000 acres in New York's eastern Putnam and Dutchess Counties--is one of the largest freshwater wetlands in the state. It has been designated by the USDA Forest Service as a Highlands Conservation Focal Area and was cited by the state Department of Environmental Conservation in a 2009 report for its unique habitat, diverse wildlife, scenic value, and its critical function as an aquifer recharge area which protects and purifies the water supply for millions of New York residents as well as provides outstanding educational and recreational opportunities.

Friends of the Great Swamp ( FrOGS ) is an all-volunteer not-for-profit group of friends and neighbors dedicated to preserving and protecting this unique and valuable resource through research, education, and community action.
