Hurricane Harvey's record-breaking flooding in Houston, Tex. this week, left nearly 300,000 people without power, many of whom expect to remain in the dark for weeks, and led 35,000 to take refuge in shelters.
After four feet of rain, many residents faced difficulty getting out of their home. Kayakers plucked treading neighbors out of the water. A midwife rode an inflatable swan to work so she could deliver a baby. And on Monday, Austin Duck Adventures brought two of their Amphibious Hydra-Terra commercial tour buses, which ride on land and water, to Galveston to join the effort.
