Last year, Hurricane Harvey dumped over 40 inches of rain in many parts of Texas. The flooding in Houston overwhelmed the capacity of first responders to rescue everyone who needed to be rescued. Enter the "Cajun Navy," an all-volunteer force of people with bass boats, jet skis, canoes, trucks and even dune buggies, who jumped in to rescue the folks that the fire fighters, police and national guard couldn't get to. And the video footage of their rescue efforts says it all: Americans are more united than we think we are. No one paid any attention to race or class, gender or religion. No one asked any questions about political persuasion or sexual orientation or country of origin. They just acted on the belief that we are one human family and we are all in this together.
