Hi Andrew - fellow UK Sox fan here. you can tell by the late night bags under my eyes!
i've had a thing for US sports since i was a kid- I used to listen to Baseball/NFL on american Forces radio when I was a kid, but interest really took off when you could start to see games live on TV. I got into them because pre 2004 they reminded me a lot of Everton and I felt an affinity with them as a result.
Have you managed to get over and see them yet? I've been a few times - amazing place. I was lucky enough to see a Big papa walk off homer at one game - man that was great.
