Question: The Oregon Trail was laid by fur traders and traders from about 1811 to 1840, and was only passable on foot or by horseback. By 1836, when the first migrant wagon train was organized in Independence, Missouri, a wagon trail had been cleared to Fort Hall, Idaho. Wagon trails were cleared increasingly farther west, and eventually reached all the way to the Willamette Valley in Oregon, at which point what came to be called the Oregon Trail was complete, even as almost annual improvements were made in the form of bridges, cutoffs, ferries, and roads, which made the trip faster and safer. From various starting points in Iowa, Missouri, or Nebraska Territory, the routes converged along the lower Platte River Valley near Fort Kearny, Nebraska Territory and led to rich farmlands west of the Rocky Mountains.

Question: Throughout the episode, numbers appear on ordinary objects counting down from 50 to 1. This is a countdown from the beginning of the episode to the eventual bad news, which is told right after the "1" is shown. As the final scene of the episode closes, a parking meter is in the background displaying a red' expired' state. The countdown was an idea taken from the 1988 film Drowning by Numbers; through the course of that film, the numbers 1 to 100 appear in order, sometimes seen in the background, and sometimes spoken by the film's characters.
