This is coming from a Cardinal fan. I have been to both Wrigley and Fenway (along with 8 other Major League parks and & 10 from the minors), and Wrigley is the better stadium. Of course any baseball fan wants to see games at both. And of course all Sox fans will enjoy baseball better at Fenway (as will Cubs fans at Wrigley).
But, if you wanted to spend one season at one of the two, and you had no rooting interest in either home team, the full season experience would be more enjoyable at Wrigley.
They have more day games, there are more good seats in Wrigley (there are some sections in Fenway which are to be avoided due to the poor visibility). The wind and lake effect result in some crazy games.
AND, nothing beats Friday afternoon, people skipping work to spend an afternoon at the ballpark, and watching the Cards win one at Wrigley.
Then hitting the town for good food and drink.
Also, I recommend 36. 18 at Cog Hill #4 & 18 at RPJN. Cog Hill is one of the great true public courses and should be played at least once. But having never played RPJN, and having laughed so hard at some of the great postings related to RPJN, it would be hard to skip, even if that is the only 18 you can play.
