"Only one thing to do here... go to the races!" Sears Point Things to Do Tip by Karnubawax

Infineon runs a full schedule of racing from April thru October. The highlight of the year is, of course, NASCAR weekend, which is the last race of the first half of the Cup season. It's almost always the last weekend in June. While the raceway runs several big events during the season, none of them come close to NASCAR in size, attendance, and traffic nightmares.

Other major events include...

AMA Superbike - usually mid-May
Wine Country Classic - vintage race cars - usually first week of June
Grand Prix of Sonoma - mid - July
Fram Autolite NHRA Nationals - the BIG boys - Late July
Indy Racing League - Late August

Ticket prices vary greatly depending on the event - anywhere from free to well over $100.
