Shannon was memorably superb. His tour is full of interesting historical perspectives and insider nuggets, and he has a true feeling for what makes this a special place. If you want to get the most out of your visit to Bonaventure, there's just no other choice. One once of caution: the cemetery is next to the river, so long pants/sleeves or spray are recommended to discourage the flying bugs.
Shannon is extremely knowledgeable and obviously puts the time in to know his material. By far the best tour that we experienced in Savannah. Highly recommended--this tour is a must!
