For us, there's Speedway Raceway, where racing is so intelligently miniaturized it gives you a super-size thrill at a teeny-weeny price. At Speedway, you'll be driving 270cc Honda-powered Indy-style go-karts around a tightly hairpinned quarter-mile indoor track. In other words, you're six inches off the ground going 50 miles an hour through turns with only inches to spare. In still other words, your adrenal glands will be squirting like high-performance fuel injectors. All this for $20 for 16 laps. Or much less with the special discounts frequently offered by the raceway. Get racing.
