I grew up going to DC Stadium, later named RFK. The dimensions were 335 LF, 380 LC, 408 to straightaway center. Today Camden Yards, even with the LF now backed up and with the same hot humid weather, is actually a little smaller. 333 LF, 376 LC and 400 to straightaway center. And the warehouse, which stands 439 feet from home plate, has only been hit once and that was in batting practice.
