"The House That Ruth Built"

Also, I'm not sure when they changed the rule, but there was a time when what would be considered a grounds rule double today was a home run.

Edit: (Rule changed in 1931): "A fair ball which bounces through or over a fence, or into the stands, is considered a ground rule double instead of a home run." (MacMillan Baseball Encyclopedia)

Interestingly, and I didn't know this, in 1926 a rule was made which stated "A ball hit over a fence in fair territory, where the fence is less than 250 feet from home plate, is a ground rule double, rather than a home run."

I didn't say that this rule was ever changed, so I presume that it remained in effect for the duration of the time that there were still stadiums with fences less than 250 feet from home.
