Lakeland, Fl-November 15, 2004-It is rumored that on November 26, 2004 Mike Cox plans to announce his "Fan Appreciation-Farewell Tour." Reliable sources have reported that he will run a limited schedule for 2005 so that he can get back to enjoying racing. These same sources claim that he will also announce the debut of a new race series. The Wheelchair Race League (sorry Mike and Kip) will feature spec prepped electric wheelchairs against "lark" type mobility devices. The lark vehicles will carry voltage restrictors to balance the performance. After the first year of competition, WCA's (wheelchair Comp Adjustments) may be made to balance performance and competition.
