This is something i didn't know the existence but it seems to have a lot of professionals racing with this mini toys on the most high level of competition with mechanics, tools, ... I got so impressed with this slot races and that is why i post this photos, is not related with the city but it's an event.
This is an hot corner with lots of cars going out of track and that is why all corners had a guy to put the car again on track.
Funny fact, i only saw a couple of real kids, it seems this is a sport for adults:)
This race was in Palacio de Cristal
