Yeah, it is. Otoh, it's always sold out, it's rambunctious, the tickets sell out during pre-sale, and the wait list for seasons tickets is measured in years. So while it's small, that's not for lack of support or enthusiasm. It's just a function of architecture.
My local team's stadium can seat around 49000, though it is rather large. It still manages to fill up. Oh and nice user of rambunctious.
