By this I mean in your Workplace/School/Home/Neighborhood etc. Basically locals... Don't go into too much detail!
None. My best friend and my brother know about it, but all attempts to get them to watch the show have failed. So ya, just me.
None that I am aware of. Anyone I know would not come out and admit they are a brony so, as far as I am aware anyways, I am a lonely MLP fan here too.
None of my family are bronies.... However, in my county, I'm in contact with about 20 bronies. But our group seems to have stopped growing... *Cri* Outside my county, I've met quite a few at meetups, and quite a few more at a convention... If that counts.
I am sad that I know no other Bronies, except my cousin, but we only see each other at thanksgiving. Other than that, one of my friend's friends is a brony, but we've never spoken. Man....
I know a lot at my college. Seven irl I guess? None of my family members are. Though I have a multitude of online friends who are.
My brother and I are the only ones I know. Buuuut I really only need one person to help me geek out about it with so it's cool
In my family there is no other brony, even no friends. But throughout some meetups i've seen hundreds of bronies. So i cant specify the correct number the bronies i know.
My wife is one, so I always have some one to talk pony to. Probably not as big of a brony as I am. And my niece is one, although she's more the age the show is aimed at, so I'm not sure if she counts or not. I've seen a couple of other bronies about town - or people who perhaps are wearing the shirts ironically or something, but something about them suggested otherwise. Didn't get a chance to ask, sadly.
Two years plus since the show started, and I still have not met a single other brony irl. Saw lots and lots of them at Comic Con, but I don't know anyone personally. I'm having good luck transforming the people around me into anime fans though. ^.^
