Mary Mungai cannot help herself from ululating. She has good reasons to be grateful to President Kenyatta and the National Government. For many years, she has been a trader at the Ruiru open air market in Kiambu County. That exposed Mary and her colleagues to the vagaries of the weather. But all that has changed with the construction of a modern, sheltered market. Mary and other traders can now look forward to a working environment that is not hostage to the seasonal sun, rains, wind and dust. She has every reason to anticipate better business and more profits.
