My 30-ballpark Geas continues into its second season. Just booked: Houston, April 7th, against the Cubs (of course).
Astute observers will note that I've visited the Houston ballpark before, when I was on a consulting assignment for a well-known energy trading company that no longer has naming rights to the park. But I decided at the beginning of the Geas that parks I visited before the Geas started didn't count. (This makes New Yankee Stadium and Citi Field problematic, so I split the difference: Old Yankee Stadium counts for the Yankees, and Citi Field for the Mets.)
My first Cubs game will be April 19th.
Update: Since I already had a trip to San Francisco planned, I've also booked Oakland for the April 25th.
