A U.S. Army staff sergeant, Travis Mills,  who lost four limbs in a blast in Afghanistan is opening a summer retreat to help those who suffered severe war injuries. The sneak peek is this weekend.

The Travis Mills Foundation Veterans Retreat Grand Opening happens this weekend.

Travis Mills says his family as much as the medical team for helping him to recover. He's paying it forward by bringing the wounded and their families to central Maine to continue their recovery.

This summer, the retreat will serve 56 families free of charge according to the Associated Press.

Mills, who's 30, says it's important for families to recover together and for veterans to learn that they don't have to sit on the sidelines while their families enjoy recreational activities. They'll do things together, including kayaking, fishing and tubing reported AP.
