OKLAHOMA CITY - You may have seen a popular superhero around the Oklahoma City metro lately. Captain America is in town and it's for a good cause.

Allen Mullins has worn the Captain America mask all over the U.S. since 2009. Instead of fighting the bad guys, he walks to raise money for veterans.

It hasn't been a walk in the park. Mullins said he's been arrested several times and gotten into some bad areas, but it's the veterans that keep him going.

When he stepped into Oklahoma City city limits, he had reached 80,000 miles.
