When we went in 2018, he was a guest and surprised us there. Hes an awesome guy (aside from being a Vikings fan) and was a critical piece to creating the grandaddy as we know it.Went back to the first GD to try and get some more info on Matt since I wasn't around back then, and realized I had never actually gone through the thread. A lot of the pics aren't around anymore, but it was easy to see how excited everyone was for the event. Pretty neat. Also really impressive how it's grown. That first one was only 66 pages seems crazy to think an experience would have that few pages now. Just goes to show when something is done the right way good things happen.
Anyway.. here is the link if anyone is interested. It's a fun read
