Credit Card Fraud

I was woken up this morning by my credit card fraud dept calling to verify my recent purchases. I'm actually surprised it took this long for them to question my coast-to-coast spending habits. Oddly enough my purchase at Fenway Park followed quickly by multiple purchases in Portland, Oregon didn't trigger their alerts, but a late-night gas purchase in Indiana followed by a yahoo bill (which wasn't mine) payment grabbed their attention. I don't understand their thinking, but I am glad they caught the irregularity although it is rough to be without a credit card for my travels. Thanks Bank of America!
