Hi I plan to be traveling to the area of the lower part of Upper Makefield Township and, especially, the upper part of Lower Makefield Township. I hope to see the Slack-Cooper-Smith House, which I believe to be located in the upper NE corner of Lower Makefield Township in Bucks County, Pennsylvania, but I don't know the exact location. I am a Slack descendant. I also hope to see Slack Island nearby. I will be traveling by car, expect to be in the area on Friday. Does anyone know the exact location? Thanks! Dave from Seattle
