Not all who paint are talented...

Practical wisdom and ???

This graffiti can be found on the walls of an abandoned house near Jordan River on Vancouver Island.

On the left it reads:
"Not all who wander are lost. Most are though."

They're not wrong.

I have no clue with the sign on the right means. I recognize the letter 'a' and that's all. Is there a point to tagging a landmark if no one can actually decipher your tag?
