Factual error: During the scene where Don Draper is having an "intimate moment" with Ms. Goldberg on the roof of the Menkens store, crickets are audibly present. Crickets are not present in appreciable numbers on a Manhattan rooftop to produce a sound loud enough to drown out traffic and other ambient noise on 5th Ave. Furthermore, the sound of the crickets is inconsistent with that produced by the native snowy tree cricket."Crickets chirp at different rates depending on their species and the temperature of their environment. Most species chirp at higher rates the higher the temperature is (approximately 62 chirps a minute at 13°C in one common species; each species has its own rate). The relationship between temperature and the rate of chirping is known as Dolbear's Law. Using this law it is possible to calculate the temperature in Fahrenheit by adding 40 to the number of chirps produced in 14 seconds by the snowy tree cricket common in the United States."
