Army of volunteers line the streets to help Hurricane Harvey victims

Volunteers are queueing up on the streets of Houston to offer their help with the Hurricane Harvey relief efforts.

The line of volunteers photographed waiting patiently in the rain is just the latest example of inspiring acts of heroism and kindness following the disaster.

While thousands left homeless from unprecedented flooding have been forced to queue up for food and water, others are waiting in line to offer any assistance they can.

Radio host Michael Berry shared the photo on Twitter with the caption: “This is Houston.”

His photo has been shared and liked by more than 300,000 times, with one responding: “So proud of Texas. So proud of the USA.”

Other acts of kindness to emerge following the storm, include Mexican bakers trapped for two days making hundreds of bread loaves for Harvey victims.
