Right field 187 row PP pretty close to the Rangers bullpen. It was the cheapest ticket that I could find but I think it was a pretty good seat.
Last year I went to a game and sat in the same general area, except I was a few rows behind the visiting bullpen, in section 43 right next to that big gap between sections. It's a pretty decent view of the field from there.
Still, even with the renovations made to the ballpark in the last decade, a lot of the seats are really uncomfortable, and a lot of the viewing angles are terrible. I don't think they'd tear it down at this point, since it's been added to the National Register of Historic Places, but I still would like to see the Red Sox build a brand new stadium. Keep the same basic field dimensions if you want, but add more seats and emphasize viewer comfort in the stands.
