What is the difference between a roller coaster ride
and crossing the Skye bridge?
The roller coaster ride takes you farther in shorter time,
and it is less expensive.
Is there a difference in crossing the alps or crossing
the Skye bridge?
You may cross the alps without paying toll.
And now a fact, not a joke: in the US, crossing the Cheasapeake Bay Bridge Tunnel costs $10 for a car - but you drive over 17 miles of engineered structure for this amount.
