I just got back from teaching a measurement seminar in Puerto Rico. A group of professional surveyors were the students.

One had extreme difficulty riding a bicycle, and on the second day he showed up with a tricycle. One other student tried it as well.

Results were not on a par with a two-wheeler, but it solved the guy's problem of getting his own data to work with. He now understands the process.
