Some of the most inspiring rescues we've seen in Houston have been neighbors helping neighbors.

As Americans nationwide band together to help show support for Hurricane Harvey victims in Texas, social media has given us a glimpse of the incredible efforts of heroic citizens already on the ground in Houston.

We've seen KHOU news crews help save a semitrailer truck driver trapped in the rising floods by flagging down Harris County sheriff's deputies for help. We've seen regular folks jumping into kayaks to usher those in need to safety. Even talk show host Montel Williams took to Twitter to express gratitude for good samaritans rescuing his wheelchair-bound colleague with canoes. Two brothers and their father from Austin came to Houston on no sleep with their personal boats to help with the flood rescues.

The common thread in all of these powerful snippets from social media is the contagious kindness of strangers doing what they can to pitch in—however they can.

Perhaps a CNN instagram video captures the spirit of Texans best. A reporter asks a good samaritan from Texas City who brought his boat in Houston, "Just jumping in to help out? …What are you gonna do? "I'm gonna go try to save some lives," he humbly replies without skipping a beat.
