Yasushi Takahashi dumped his girlfriend and quit his job to go on a 6-month road trip across Japan, with the goal of creating a grand marriage proposal. Equipped with a GPS, Yasushi traveled 7,163 km (4,450 mi) mostly on foot, but occasionally using a car, ferry, and bicycle. When he returned home, he transferred the data to Google Maps, revealing the result as the words "marry me." This has earned him a certification from Guinness World Records as the largest GPS drawing worldwide.
