L’maaseh it’s not a kosher activity. You’re telling me yeshivish people do go. Personally, I was brought up to not go to baseball game. I went to a baseball game when I was in camp about 15 years ago. That was about it. However, it’s not a kosher activity, being with non jews like that and the people there aren’t exactly the type of people you’d want to hang around with. There are also issues with Lo Selech B’chokos Hagoy.
zehavasdad, there are other issues besides for the ones I just mentioned when going to basketball and football games and that is that there’s definite pritzus as there are cheerleaders.
It’s definitely not in the sppirit of Chol Hamoed. In major cities, they try to have a big attraction on Chol Hamoed so people won’t get bored.
