This is gonna be tough...
I have done every event from 1999 through 2008. I skipped 2009, and havent been to 2010 yet...
I do not think I could put them into order...Some years were better to me than other years..
I must say, my first year, 1999 ws my best...it was all new and exciting then. After the event was over, I ended up with a sore throat and no voice for 2 days I screamed so much.
Other favorite years..The first year at IOA, the year it was split between the 2 parks, and the year of Freddy, Jason and Micheal...I was scared silly by Michael Myers in his house numerous times..he got me really good..
Havent been so far yet this year...can't wait and have high hopes.
