Scuba divers, not so much. Imagine the smell.
Of the seals I mean

An invasion of sea lions at San Carlos beach in Monterey forced city leaders to close the beach Monday to all users, indefinitely.
“This is one of my favorite beaches to hang out on, on the lunch break, so I can’t go there because it’s partitioned off, but yeah, I love it,” said Teresa Jones, of Pacific Grove.
Barricades have been put up, preventing beachgoers from accessing the beach. The area is also a popular spot for scuba divers and diving lessons; the sea lions force them out as well.
“So there’s actually a really great, another beach just about a mile down the road called McAbee Beach, and so we’re just sending divers over there, and they’re perfectly happy to just go a little bit extra to get in the water still,” said Megan Patton, of Monterey Bay Scuba.
Shoreline docents who regularly monitor sea life say the sea lions started arriving last week, about 20 of them, but by Sunday night, there were hundreds of them.
