Yes, my kids love our local AA baseball team. Tickets < $15, various bounce houses and generic carnival type things for the kids, but something to break up the game for a bit when they get tired of sitting. No idea what an equivalent MLB outing would cost, but I don't care either as the closest one is 3-3.5 hours away, vs. 20 minutes to our AA ballpark.

Orioles are dirt cheap if you want to take the MARC up for some baseball, though. And the MARC itself is 7 bucks

Do they still have the very cheap but surprisingly good hotdogs right outside the stadium that you can then bring in, which keeps prices inside somewhat in check?

(Reminiscing over the $5 student tickets available with college ID in the early 2000's)

Nats tickets aren't bad, it's parking/transit and then food/drink that are the killers. I guess you can skip the concessions, but that's part of the fun, IMO.

Word, baseball isn't the same without a nice cold beer.
