Oh! I discovered this brochure at the NYS Parks, Recreation, and Historic Preservation website: it's the Guide to New York State Historic Parks. It's in a PDF format that you can download off the web. Look for the small icon of it in the left hand side of the screen at the NYS website. It's terrific!

We have been to dozens of historic sites across Upstate New York. The state has done an absolutely superb job with the parks, really. Some of the parks are perfect for comfortable strolling or browsing, others are real muscle builders with their trails and activities-- but ALL are in great condition, and ALL are incredible resources. I have found the employees at these parks to be so friendly, generous, and knowledgeable. We love visiting the parks, and I can't wait to go again!
