“It’ll change your life.” That’s what someone told me about the trip to Mozambique in April....

On January 28 it was a nice day in Columbia, with a high of 74 degrees. The next day there were severe thunderstorms. Two days later it was down to 4 degrees. For most people, extreme swings in weather mean you’d better check the forecast so you grab the right coat before you leave for work in the morning. For the homeless, changes in the weather can be fatal.
