People unclear on the subject - tubing on the river

From Michigan Live:

Muskegon River tubing trip turns into overnight nightmare for three women
They left for what they thought would be an easy float down Muskegon River Tuesday afternoon – but ended up spending the night on the river bank, scared and yelling for help.

The trio of young women were rescued 20 hours later after a fisherman eventually heard their cries, said Muskegon Township Deputy Fire Chief Bob Grabinski.

The women, all in their 20s, had never been tubing before and decided it would be a fun thing to do, Grabinski said. So they bought some tubes and headed to the popular launch site at the Maple Island Road bridge, Grabinski said.

"They were informed by somebody at the bridge that the river goes in a circle and if they put in there they would come back to their car," he said. "Not knowing anything, they set off on their little adventure."

Talk about gullible. Glad they are OK but sheesh...
