I am glad that when I was about 13 or 14 my aunt took me down to Tiger Stadium from London. I have seen very few MLB stadiums, but I am glad I got to see TS before they built Comerica. I even got to watch my cousins ride the merry go round!
Also seen Skydome, SF Park, where we sat in right field (not a single jack into McCubby tho

), and this summer Safeco (boy is my head ever gonna hurt from those freaking trains).
I have always wanted to the 30 stadiums in 30 days trip.
