Tom Voss and Anthony Anderson started their five-month journey across the country in Milwaukee where the two veterans live, and will end their walk on the Santa Monica pier at the end of Route 66.
The pair about 20 miles a day, sometimes through inclement weather, and they ran into a few delays due to injury and fatigue.
They plan to make a documentary of their walk which they will use to raise money for Dry Hooch, a drug-free, alcohol-free organization that helps veterans who suffer from PTSD and depression to get the help they need. Voss and Anderson were both diagnosed with PTSD after serving in Iraq. They have a goal of raising $100,000 for the charity and have about $75,000 so far.
They will cross the finish line at 3pm on Sunday on the Santa Monica pier.
