American GP rounds have been happening for over forty years. Here's a handy guide to USGPs of the past

Year: 1964
Circuit: Daytona International Speedway
Details: The first GP run in America was organized by Bill France at the Daytona Speedway. Daytona's relationship with the AMA has always been rocky and there's little doubt one of the motivating factors in holding the GP race was to put one across the bow of the AMA. The USMC actually sanctioned the event as the AMA wasn't part of the FIM back then. The AMA didn't allow "their" riders to race the FIM GP class because those bikes featured the incredibly dangerous full fairings.

MV Agusta-mounted Mike Hailwood won the first USGP. Little known fact: Hailwood almost had his hinnie polished in the first USGP by little Argentina lad Benedicto Caldarella on a zippy Giliera. Caldarella's Gilera had everything and more for Hailwood until its transmission stopped transmitting.

Year: 1965
Circuit: Daytona International Speedway
Details: Hailwood dominated this race; his margin of victory? Two laps Legend has it he stopped late in the race to chat with a cornerworker. Then re-started and crossed the finish line. American Buddy Parriott finished second.

Year: 1967
Circuit: Mosport
Details: Okay, not in America but a cool race nonetheless. And it is on the same actual land mass as the US.

Year: 1988
Circuit: Laguna Seca Raceway
Details: Grand Prix's triumphant return to the US in 1988 featured an emotional win by 'four-time Eddie'--Eddie Lawson.

Year: 1989
Circuit: Laguna Seca Raceway
Details: As cool as the 1988 race was, the '89 event was as horrible. Several riders left the circuit in plaster including Honda's Wayne Gardner. A cool-off lap crash ended the career of talented and likable Bubba Shobert. The 1989 race was as bad as it got--until 1993. Wayne Rainey won the race with Kevin Schwantz and Eddie Lawson behind him, although EL never made the podium ceremony.

Year: 1990
Circuit: Laguna Seca Raceway
Details: Rainey again won the 1990 race, with Schwantz and Frankie Chili joining him on the podium. Crowd numbers dwindled.

Year: 1991
Circuit: Laguna Seca Raceway
Details: Rainey again on top, making him a three-time winner here in Grand Prix. Mick Doohan finished second and Schwantz third. The '91 race was, of course, the one in which Kocinski crashed out of the race, jumped in his rental car and soon enough found himself in handcuffs.

Year: 1993
Circuit: Laguna Seca Raceway
Details: Held just a week after Wayne Rainey's infamous Misano crash which ended his career, the '93 USGP was promoted by Kenny Roberts and had a pall over it as news slowly broke that Rainey would never walk again. Fans didn't exactly line up in droves to attend the race, and even Roberts laughed when he saw the "official" crowd count numbers.

Year: 1994
Circuit: Laguna Seca Raceway
Details: Held on September 11, Rainey's teammate, Italian Luca Cadalora, became the first non-American to win a GP on US ground since Hailwood.

Year: 2006
Circuit: Laguna Seca Raceway
Details: In front of a massive and sun-broiled crowd, American Nick Hayden wins the second-ever MotoGP event in America.
