"Apart from cheese and tulips, the main product of the country is advocaat, a drink made from lawyers," claimed Alan Coren of Holland in The Sanity Inspector, 'All You Need to Know About Europe.' (1974). Perhaps, but in gratitude for sheltering members of their royal family during World War II, the Dutch made a gift of tulip bulbs to Ottawa. Canada's drab, grey bureaucratic heart has never looked back. Every May the city's parks and gardens come alive with hundreds of thousands of tulips, the world's largest display. Not a wonder that Canada's capital is rated among the world's twenty most livable cities.
