In 2003, the season expanded to 16 games. There were also several rule changes in this period. In <answer>2005</answer>, players were no longer allowed to run out of bounds. The only way for a player to go out of bounds presently is if he is tackled into or deliberately contacts the side boards. This was also the first year the ArenaBowl was played at a neutral site. In 2007, free substitution was allowed, ending the "iron man" era of one-platoon football. And in 2008, the "jack" linebacker was allowed to go sideboard to sideboard without being penalized for "illegal defense".
In what year was the ArenaBowl first played at a neutral location?
2005
