For those of you unaware, the new Strip in Vegas is a little over 4 miles long. The old Strip, Fremont Street, is located in the old part of downtown. Fremont is about a 5 mile hike from the eastern end of the new Strip.
The Tropicana is on the western end of the Strip. So Lorne, Gunn, and Fred walk out of the Tropicana and end up almost 9 miles away.
