Hi Markku. Lucky you getting to do this during the day. The Go karting track is good fun. We had an office Christmas party the one year doing it and became highly competitive. They can go slightly faster than what you say but they put a limiter on them for safety reasons. They seem like they go faster because you are basically sitting on the ground. They are very low. Small little towns are beautiful as they are usually unspoiled by development. Lucky to have places like that still around.
