I took my boys to Gene Woods in December ( we drove from Walnut Creek to Vegas) and I bought the coupon from Groupon as a stocking stuffer. This place was amazing! Such a great experience, the go kart were bigger than the boys ( then 14,15 years) thought and they go fast! They had so much time to race. The staff was wonderful and even took my camera out in the middle and photographed them. I tipped the guy 20 because they spent the time, went above and beyond. This was a perfect experience for my boys. We were not rushed and they will remember this forever. (I grew up by Long Beach, Washington so my boys had always rode the go-karts in Long Beach growing up when they visited Grandma) Gene Woods (outdoor not indoor) was hundreds times better/bigger and faster. - Thanks Linette, Dillon and Kurren.
