How cool! I've never heard of this, but it is not the first one. There is a Deadliest Catch Fan Festival. This years event is at the Bell Harbor Conference Center in Seattle on April 9th from 12p-6p. I wish I lived closer to Seattle. I would be there! Go here to register for the event.
At Catch Con 2011 you get to meet some of the captains and tour the fishing vessels of the Deadliest Catch Crews and best of all its FREE. Yes free, you don't see that very often.
If your not in the Seattle area you can watch the event live by going to the Discovery site.
There are clips of the Deadliest Catch Catch Con 2010 up on the site now.
