For non-Origins things in Columbus, I recommend the replica of the Santa Maria and the "children's poetry park" (both walking distance from the convention center). I've never been on the ship, but it is easy to see why the sailors mutineed in those days: absolutely open deck, and so fat that she must have rolled like a pig in high winds. (Admittedly I am biased towards longships, but I think most people would shudder at the living conditions on that vessel.) The park is near to the ship, maybe a block away. There is a story told on plaques, with footsteps to follow around, and lovely bronze sculptures. Carolly
