Sonoma Raceway will host one of the world's most unique endurance races this weekend as the 24 Hours of LeMons hosts its season finale on the wine country road course, Dec. 7-8.

Put away any preconceptions of sleek-bodied, turbo-charged, million dollar pieces of engineering brilliance and prepare yourself for the likes of RVs going toe-to-toe with Porsches and Pintos battling BMWs. Plus, all entries must cost no more than $500 to purchase, fix-up and prepare. This is a one-of-a-kind race, that's got to be seen to believe.

Prepare for plenty of noise, wacky penalties and questionably civilized fun before, during and after the on-track sessions on Saturday and Sunday. Race officials often wear powdered wigs and the winner is paid in a sack full of nickels.

Nearly 200 cars are entered for the 24 Hours of LeMons' final event of the season, which featured six events on the West Coast in 2013.

"America is the land of opportunity — all you need is one bad idea," quipped Jay Lamm, a Bay Area resident and series founder.

While all this foolishness is primarily done in the name of fun, it's also done in the name of charity, as a portion of proceeds benefit Sonoma County non-profit organizations through Speedway Children's Charities, the charitable arm of Sonoma Raceway.

Spectator tickets are $30 each and kids 16 and under are admitted FREE. The weekend will feature racing from noon-5 p.m. on Saturday and 9 a.m.-5 p.m. on Sunday.  For more information on this wild and wacky series, including the official "How Not to Fail Tech Inspection" guide, visit 24hoursoflemons.com or on Twitter @24HoursofLeMons.
