I have put my "99 Places Every Antietam Battlefield Guide Should Know" online. It is a work in progress and is currently a bit of a mess, but I thought it would be fun to get suggestions before I spent too much time adding some new places I have learned about. For the record, this is not a list of obvious places a guide should know. These are those special places that guides have discovered that are fun to share with those who really care about minutia.
