unlucky!
I travelled over to America a few years back. Had a couple of games lined up. The first was at Yankee stadium. We decided not to go to the game on the day we arrived as we'd be too tired from a long flight. That game was an 8-7 (ish) thriller. Game next day was rained off. Went for a tour of the stadium at least a few days later, and was told it was closed as they were shooting a movie. So fudge the Yankees. Lesson learned, ALWAYS go to the first available game.
Had booked a seat behind home plate in Tampa. Really underestimated how difficult it was to get there from Disney. After way too much angsting about whether or not to go, I decided I had already paid good money for the ticket and given Yankees was rained off it was my only chance to catch a game. So forked out the ridiculously high taxi fare to and from the game (talking $100s)
Due to my angsting, I also turned up at the bottom of the 1st. Was walking up the aisle to my seat, just out of view of the ground, when Evan Longoria hit a solo home run. Was fun seeing the croud cheer etc, but ultimately didn't see it. Was disappointed but figured there were another 8 innings. The Rays won 8-0 and there wasn't a further home run.
So am yet to tick "watch a major league home run" off the bucket list.
