Lynda Crackett is right. My sister and I have ben chasing this situation for the last year. In 1670 to about 1760 people settled in Vermont used Lake Champagne for travel, both east and west, and north and south. It just depended on who had control of it at the time, (French, English, Indians, or locals) plus the Indians used it for bot fishing and fighting.
Put your roadblock up for us to see and in our investigation in trying to figure out our roadblock, we may run across something to help you and others that are looking for the same answer.
Have fun, Richard Reed 9427
