Not in Kansas
I picked up a little scrap of paper from the floor of our car and came across this little note. To help your powers of interpretation, the bottom lines say, "Swimming - hippos? crocs?"
We went on a weekend getaway possibly featuring a swim in the river. It struck me how non-USA it was to need to ask if there were hippos or crocodiles in the river before we could swim.
There weren't any. They had to quit rafting a few years back, though, because hippos attacked a raft or two. (The "beach" was hippo-free, however.)
The water was cold!
