1. A scenic route around Michigan's Upper Peninsula, which is also known as the "U.P." or "Yoop." Motorcyclists are especially fond of this semi-wilderness experience.
2. An alternative route from Wisconsin to lower Michigan. Instead of slogging through the heavy traffic of metro Chicago, adventurous drivers can take the "Yoop Loop" over the top of Lake Michigan and then across the Mackinac Bridge to lower Michigan. Longer, yes, but way more beautiful.
3. A generic term for any trip that takes the traveler through Michigan's Upper Peninsula en route to somewhere else -- one of the great undiscovered pleasures of the North Country.
"Don't drive through that traffic mess in Chicago. Let's take the Yoop Loop instead."
"What if our car breaks down and we're attacked by bears?"
"It's better than being attacked by gang bangers on the Dan Ryan Expressway!"
