On the Highway near AL Sajjad Hotel before "Toll Plaza" is a ROAD, on the left side of it is a track for Ultimate Go cart racing..
Its a professional track. It costs around 500 to 700 RS for racing for 15m ... but let me tell you 15m are not less. The experience is worth it:)
Its a good thing that now we have variety of hangout places in Khi.. Ice Skating then Go Aish Park and this Drag Raching..all of a sudden there seems to be a lot of choices and diversification in Khi:)
