I have been to Fenway Park countless times, first time was in 1992, the most recent was last Sunday against Tampa Bay. I've been to four games at Sky Dome/ Rogers Centre, once in 1999 (Wakefield v. Clemens) and for a 3 game series in September of 2007, where the Red Sox were swept. The highlight of this 3 gmae sereies was leaving early after the 3rd game and being taunted by a "Yankees" fan who said in the thickest Caanadian accent of all time "Nice little 3 game sweep, eh?" To which I replied nice 3rd place finnish. He then said I'm actually a Yankees fan, I've got seasons down in the Bronx. The odd part of this was the Yankees where playing in New York that night.
As for minor league parks I've been to McCoy and Hadlock when the Sea Dogs were still affiliated with Florida
also, have to agree about the wave, I'm about 99.9% sure Fenway is the only place that still does the wave, I think everyone else stopped in the mid 90's.
forgot to mention Doubleday field in Cooperstown, NY
