Rotary International is over a million members in about 13,000 clubs world wide. They meet once week for a meal and a drink. They also raise money for charity. They have become the world's experts in providing emergency relief. Go to ShelterBox, Rotary and Polio or Jaipur Limb for just three examples.
They are often the first organisation to get help into a stricken area and often the last out.They do not squander donations on 'overheads' or 'expenses'; all proceeds go charity. Rotarians are mostly successful people who want to give something back to society. They have fun!
