For much of my life I wasn't much of a sports fan. Probably anti-sports, really. I'm still not a megafan - there are times when I watch a reasonable amount of baseball, and times I don't - but I at least understand sports fandom in a way that I didn't once upon a time.
Still even without getting it, Philly fans are a bit wild in a mostly entertaining way. City was shaking just for... the Phillies getting past the wildcard round.
