Nick Lundgreen was injured in a crash at the Prairie last year. His dad has the family midget for sale and Brad Kuhn has taken over the seat in the Jones Motorsports car.
I don't know if he plans on coming back, but it sure doesn't look like it. I believe I saw him working on the Pedregon crew at Tulsa this year.

Kenny Biro's website says that he is out of driving for the foreseeable future. His focus will be on his studies as he hopes to graduate high school on time and enter the
engineering program at IUPUI.
