I love the terrace left field seats. I only get to a handful of games a year, but when I do, I try to get tickets from ebay in the front row. Sections 103 and 104 are my favorite. You're so close to the action, you can see everything, and it's prime home run territory. And also Dunner is right there so that makes the view all that much better!
I will say, however, that I don't like those seats for day games. You're in the sun the whole time and it's terribly hot. I got fried there this summer.
