You East Coasters got it easy..
Your predator is confined to the water.
Out here in Oregon, the predator will chase you out of the water, take you down as you run screaming up the beach... Then drag you behind a sand dune and leave you to ripen a bit before feasting.
Cougar Sighting,
A cougar this week was spotted climbing on Oregon’s Haystack Rock near Canon Beach OR. It caused the beach to be vacated and the town to be on high alert.
The cougar swam around, then left the area.
