The drift demo is on March 7-8 during the Super Chevy Show. I'd rather go to the Chevy thing since there will be drifting and Nitro Coupes, which have about 2500 hp and run the 1/4 mile in the low 6's @ 230 mph.
Also, Super Chevy Show is a national event, so SFL is getting sick exposure. Import Showoff is also national, but Import drag racing is dying... or dead.
