My dad entered a lottery for tickets the year it was at Camden Yards ('93?). And he won. I don't know how it works now, but you got tickets to both the HRD and the game itself then. He gave the tickets to my brother & I. And I still don't know how he did it, but he got us rooms at the Holiday Inn right at the Inner Harbor.
The Derby was a blast. Juan Gonzales won, IIRC. I've been going to MLB games for 50 years now and he hit the hardest ball I've ever seen. It hit the facade of the upper deck in left field and was still going up. But the biggest cheers went to Ken Griffey, Jr who hit the Warehouse and broke a window.
