I was huge comic book fan for many years. About 20 years ago I probably had over 5,000 comics (mostly Marvel). I pretty much gave them up after my first child was born and eventually sold most of them. I still have maybe 200 left and my youngest got into comics a few years ago. I buy a book here or there and read some of hers.
I actually went to my first Comic Con in Rhode Island this month. I wasn't too interested, but my daughter really wanted to go. I have to say, it was fantastic and I wish I had gone to one sooner. We may go to a larger one in Boston or NYC next year.
