SPOILER ALERT! "LOST" returned to the Windward Community College campus in Kaneohe today to film another scene at the "Santa Rosa Mental Institute." A sign was set up in back, fronting a sometimes soccer field, and Jack's old pickup truck was parked nearby. Filming took place inside Hale Kuhina, the continuing education/employment training building, with Jorge Garcia and Matthew Fox. A man dressed as a doctor (Dr. Stillman, perhaps, given recent casting calls) and a couple of burly orderlies were also sighted milling about.

Hale Kuhina is within a stone's throw of the Hawaii State Hospital building and shady tree that served as the Santa Rosa lawn where Hurley received a mysterious visit from Charlie.

Check out a few more photos here.

Special thanks to "Grappler" for the walkabout!
