Easy 5 mile flat, urban walk. No sticks or heavy duty boots needed. Fort McHenry entrance is free. Park in the lot nearest to the Visitors Center, where there are excellent bathrooms. We'll circle the Fort, then head to Under Armour, (Tide Point Landing), catching the 10:45 water taxi to Canton. We'll walk a quick 1 mile back and forth along the water and take the 11:30 taxi back. From there we'll eat our lunches in the Riverside Park area.…
