The meeting point is the horse statue at the top of Vรกclavskรฉ nรกmฤstรญ between 4.30 pm and 5 pm. De-clothing will take place a few minutes before 5 pm and then people will head into the metro.
Participants will ride around on the metro for about one hour, probably just doing the loop between Muzeum, Mustek, and Florenc, before heading for a refreshing drink around Namesti Miru at 6.30 pm.
The no pants rides started out as a harmless prank in New York City, and has since spread across the world, with dozens of cities participating every winter.
