My friend bought a pre-loaded card at Costco wayyyy back and wanted to use the card. Do I want to try go-karting? OK! Let me state first that I have never go-karted before. I had a great time and was glad the place wasn't crowded (we went during the week during the mid-afternoon).
Cost: $25/race (each race lasts 10 minutes). Mandatory headsocks available for $2 each (can bring these next visit). Lockers are $0.50. There were a couple of vending machines with the usual products for the usual jacked-up prices.
The track itself wasn't extremely complicated (see photos). Prior to racing, we had to watch a safety video (no bumping....green pedal is the gas pedal, red is the brake, etc.). Then we chose our helmets (Small through XXL) and gloves and were directed to our karts. The place looked clean enough and the staff were really nice.
I can't imagine doing this in the summer! There's a lot of heat generated by the karts. Definitely go during the winter. This would be a fun group outing during the holidays if you wanted to spend some Christmas cash.
Wear closed-toe shoes! No sandals/flip-flops allowed!
