The other day I was using Elmeaux's 'phone number' method to memorize all of the notes
on the fretboard and wondered how I could find the specific fret position more quickly.

I then remembered that I had a collection of dice of different configurations and thought I could use
those to help quiz myself in finding fret positions.

I took out a 12-sided die and I would roll it to get a random number and then try to quickly find
that fret on my bass. That works great for the first twelve frets, but I have 24 frets on my bass
and wanted to go further.

I didn't have a 24-sided die, but I did have a 30-sided die, so I started using it and just
re-rolling the die if it comes up with a number greater than 24.
