Recently, the Technical Difficulties discussed the \$100 hamburger on their show Citation Needed.
A "\$100 hamburger" refers to the practice of flying to another airport, eating a hamburger there, and flying back again.
The hamburger is used as an "excuse" for flying — the actual reason is just getting flight time to meet minimal flight hours. Presumably, it once cost around \$100 to do this, which is a lot for just getting a burger.
The Wikipedia article mentions that a hundred dollar hamburger actually costs more than \$100 these days, due to increased fuel prices.
Is it feasible to accomplish this mission (in the United States) within a \$100 budget today?
