For any of you folks who are interested there are monthly TSD (Time/Speed/ Distance) rallies in So. CA. These rallies are about 2 hours long and cover about 40 miles. They are done on normal streets AT or BELOW the speed limit. The cost is $10.00 and the only equipment you need is a watch (wristwatch is okay), a car, and a friend. Registration is at 7:00 pm and the first car out is 8:00. These rallies are on the first Friday of every month and start at the corner of Sepulvida and Devenshire in Northridge (behind the Bank of America).
Cars leave one minute apart and follow the same course. Basically, the competition is against the clock.
Give it a try once and you'll keep coming back!
