When your get picked up by a Taxi Cab at McCarran airport in Las Vegas, Nevada and get taken via the airport tunnel to "The Strip" you just got tunneled most likely. Another way of saying you just got screwed. Sometimes taking the tunnel to I-215 West to I-15 North makes sense, but not very often.
That $%*@'ing cabbie last night sure tunneled me taking me to the Hard Rock. :-(
