You don't need to be a health care worker to value the work they do at LAC - Rancho Los Amigos National Rehab Center. Ask whether a tour is available for an educational wander through the facilities.
LAC - Rancho Los Amigos National Rehab Center is regularly visited by travelers to Downey. But this health care facility shouldn't be your only stopover in the area. Citadel Outlets is nearby and worth a look.
