I am but I'm not hard core like some people are about it. I've not been to a con (though AC is pretty close for me, like 5 hours drive). After high school I was really into it and then when I got into my 20's I became more of a generic nerd. Mostly computers and comic books.
I have a friend whom I met on TLK.org's message board way back when (over 10 years ago) and we ended up going to NYC to see TLKoB. He goes to something like 6 cons or so a year and there are a bunch of furs in his general area that all get together and do stuff all the time.
