We live in Baltimore county and were looking for something fun downtown with the kids. We've done the aquarium, tall ships, etc... then stumbled on this free tour so said what the hey. It was SO good. Our guide Brian was great with the kids and entertained us, too. We're not history buffs, but he has some wild stories about Baltimore. Pretty cool. Never thought I'd enjoy a walking tour so much. Left him a nice little tip, as it seemed only right for a free tour. Highly recommended.
