It sounds as though defensive end Justin Smith has not left the Bay Area just yet.
From Miocco's blog:
Justin Smith is still in the Bay Area. He took a helicopter tour of the South Bay this afternoon with Mike Nolan. He will have dinner tonight with Nolan and, perhaps, a few coaches. I just spoke with Smith's agent, Jim Steiner, who confirmed the helicopter ride and dinner tonight. He said he was not sure who would be joining Smith and Nolan for dinner. Steiner said Smith is still "scheduled" to go to Minnesota tomorrow. But it's pretty clear the 49ers are going to pull out all the stops to sign Smith before he has a chance to leave the Bay Area.
