I'm going to read about whether 60,000 people could beat Safari zone later in the morning. They managed to catch a Rhyhorn, before using up the rest of their Safari Balls. I don't think 60k people will be able to work long enough to walk through the entire Safari Zone. I'm not sure how many attempts they've had at it yet, but there's a lot who want to see it done. It's the only place that could create a real dead end, as you need the HM and Gold Teeth from there, but it costs money to visit as well.
