From a press release:

TrackAddix Racing, Track Days and School of Speed has booked a track day and school event on the weekend left vacant by the cancellation of the AMA Superbike round at Brainerd International Raceway. TrackAddix originally had an event scheduled on Monday, June 27th following the AMA weekend.

According to Dean Rumfola, owner of TrackAddix, “We have had many requests for a weekend date at Brainerd. Weekends are very hard to come by at certain tracks and we saw this as an opportunity to better serve our customers.”
In addition to racing with the MRA, CRA, and CCS, TrackAddix also provides motorcycle track day events, a suspension tuning school, and a roadracing school.
