I unexpectedly found myself overseeing a 10yr old and 6yr old, and their mother asked if I'd take them go-karting. There is a kart place on the outer ring of Lynnhaven, so we went; and the minimum age for a driver is 8, so I ended up as a co-pilot for the 6yr old in a side-by-side kart.
$20 and a Groupon gets you two races at ten minutes each. You put on a "head sock", a neck brace, and a helmet, and squeeze into the kart. They give you a briefing on red flag, yellow flag, etc, but in fact the only signals we got were "when the lights flash, take one more lap and pull into the starting row." The attendant pulls the starter cord and away you go. The helmet restricts your peripheral vision quite a bit, so if you don't look over your shoulder, someone can be right behind you and you won't know it. The karts can hit 45mph and (when someone slightly more expert than I am is driving) can drift and do a bootlegger reverse. Steering takes quite a bit of effort, although the attendant said the single seaters are easier. At the end, you get a printout which shows your fastest lap and average time per lap (yes, the ten year old beat my Fastest Lap by about half a second).
