Okay, so I'm a New Englander and therefore a requisite Red Sox fan. Have been to the storied Fenway Park many times and have always had a good time. I've also been to several other MLB parks.
I must say that this park tops them ALL. What an incredible value! At Fenway, you pay through the nose for uncomfortable seats with crummy views of the field. Here at the Great American Ballpark, we paid a ridiculously low amount of $27 each for GREAT seats overlooking the first base line. We could see all the action. Not to mention, parking nearby was free, with only a $1 bus fare. (you're lucky to get $20 parking in Boston)
We enjoyed fireworks after the Friday night game (which the Reds won, against the Padres, yay!).
Will definitely make a point to see another Reds game on our next visit to KY/OH!
