It might even help us with our genealogy. Perhaps when you were there you took pictures of tombstones or made rubbings. Extra time on your trip should be used for something fun or to locate more information, not to learn something you could have learned at home. Great Uncle Homer might know all the family trivia, but he might not be much help in using your camcorder. Learn before you leave home.
Many genealogists have computer files that contain their family information.
Many of us have made mistakes with these files. Some of these mistakes we are aware of and some we aren't. Of the ones we know about, some we can fix and some we can't. The mistake can be a minor irritant or significant enough to make us consider starting all over. Maybe we should allow ourselves the ability to practice with our genealogical database as well.
