Arnold Hastings and Art Diaz each took a pair of victories during Sunday’s CCS event at Summit Point Raceway, near Washington, D.C.

Hastings rode his www.smisigns.com-sponsored Ducati 999 to wins in the SuperTwins and Formula 40 races. Hastings also finished second in the GT Lights race, which was won by Diaz on his Schaeffer’s Harley-Davidson/Buell XB-12R. Earlier in the day, Diaz piloted his Buell to a win in the Formula 40 Lightweight race.

Other race winners on Sunday included Loikits Industries’ David Loikits, who came from behind on his Suzuki GSX-R1000 to beat Justin Marm in the GTO race; young gun Patrick “P.J.” Jacobsen, who ran away with the 125cc Grand Prix race; Harley-Davidson/Buell of Frederick’s Bryan Bemisderfer, who took advantage of an error by Deeley H-D/Buell’s Dave Estok to win the Thunderbike sprint; local rider David Rose, who rode his Castles-and-Cottages Yamaha YZF-R6 to a win in the Middleweight Grand Prix race; and Mike Himmelsbach, who took his Himmelsbach Racing Triumph Daytona 675 to victory ahead of Butler Machinery’s Robert Jensen in the red-flag-shortened GTU event.

The day was marred by two incidents. First, Mike Himmelsbach’s father Bill Himmelsbach highsided his Yamaha TZ250 during the GTU race. He was knocked unconscious in the fall and transported to a local hospital by helicopter. Himmelsbach regained consciousness and was alert and responsive to safety workers before being loaded onto the helicopter, according to race officials.

The day ended early when a severe thunderstorm hit Summit Point Raceway. In fact, some race officials reported seeing a funnel cloud over the racetrack. During the storm, extremely strong winds ripped through the paddock, destroying canopies and pulling away a section of the timing and scoring building’s roof.
