I'm betting this topic has been discussed before, and if so please forgive this new subscriber asking again. We're the owner of a small historic home with that was the home of Mary Todd Lincoln's sister) and are developing policies for new interpreters. We have a policy of not allowing photography, but wonder if this is overly restrictive. We currently only have visitors touring a couple of times a week, though with the opening this year of the Abraham Presidential Library we are getting more visitors and we plan to promote harder. What are the policies of similar historic homes?
