A new way to learn guitar

Ever have trouble remembering the notes on the fretboard.  Sure we remember some but the process of learning the fretboard can be a daunting task.  Sure you have cheat sheets or theory books with a diagram but that isn’t always handy. 

One guitarist decided to take it to the next level. He  always has a fretboard diagram with him.  How did he do this?  He had it tattooed to his arm.

The tattoo was done by J & J Elite Tattoos.
