Olympic Games will take place on the Moon

Kenneth Gatland : writer
With colonies living and reproducing in lunar cities, the climate might be perfect for the first ever interplanetary Olympic competition. The stadium for the event will be situated under a huge Plexiglas done, and Earthlings and “Moonies” (lunar families) can come and watch the event take place. With lower gravity, certain events like the high-jump would be even more entertaining.
