I have find two Redcliffe cities in the world, one of these is in Australian and another is in Canada. I don't know what of these city is that the letter explains, probably, I think, is the Australian city
One Redcliffe is a residential suburb of the Moreton Bay Region in the north-east of the Redcliffe peninsula, approximately 28 kilometers north-northeast of Brisbane, the state capital of Queensland, Australia. The city's name originates "Red Cliff Point" named by from the explorer John Oxley. Redcliffe became Queensland's first colony in 1824. Since the 1880s, Redcliffe has been a popular "seaside resort" location due to its proximity to Brisbane.
Redcliff, in Canada, it has a rich history which began in the 1880s with the discovery of abundant coal and natural gas reserves. Easy access to this inexpensive resource led to Redcliff being called as the "Smokeless Pittsburgh of the West". This industries produced such diverse products as shoes, gloves, cigars, trucks, bricks, glass, flour and more. A cyclone that ravaged several of these businesses started the decline, and the war and a flu epidemic ended the prosperity. But now Redcliff remains grow progressive and currently boasts a population of almost 5,000. The town of Redcliff is known as "The Greenhouse Capital of the Prairies" because has long hours of sunlight, inexpensive natural gas and proximity to the TransCanada Highway all contributed to the establishment and success of the largest concentrations of commercial greenhouses in Western Canada. There are over 50 acres under glass or plastic. Cucumbers, tomatoes, and peppers are grown in abundance.
