He made sure he didn't get lost like he did Friday when he took the wrong train and wound up at Shea Stadium in Queens before finding his way to the Bronx.
Reggie probably remembered the 7 train got him to the ballpark last time and if it worked then, it should work now. After all, it must be the "Ballpark Express" and being so - it should go by Yankee Stadium.
If he did, it's completely understandable and not uncommon.
Dan, what can I say, you tried.
