ENGLEWOOD, Colo. -- A lesson in how to use a wheelchair was never something Michael Caster thought he would need.
He is one of the hundreds of seriously injured in the Las Vegas shooting, now going through intensive rehabilitation on a journey that could last a lifetime.
"I have a lot to be thankful for. I could have been one of those people that didn't make it here," said Caster, who put his body in front of his girlfriend's during the shooting.
They now know that a bullet fragment went into his spine, and he currently has no feeling from just above the waist down.
"Oh my God. He's the strongest person I've ever met and known," said Tawny Temple, Caster's girlfriend, who said they chose Craig Hospital because it is one of the top spinal cord rehabilitation centers in the country. "If there is any hospital that's going to work miracles and do the best at what they do, it's this one."
His sister is also by his side and is worried that now that the attention on the shooting has dwindled, people will forget the lives forever changed.
"I know he'll get through this," said Jodie Osisanya, Caster's sister. "And I just wanted people to know that this is still real for us."
For Caster, the focus is on his recovery -- going as far as he can possibly go.
"I'm just focused on what do I need to do to heal -- eyes on the finish line," said Caster.
