Kauai is a small place; it is the least populated Hawaiian island with only about 65,600 people.
The South side was full of resorts and sunshine, but the rainier, more rural Northern side had some great local spots. And with small, local establishments comes interesting, handmade signage.
In fact, I noticed that not very many signs were actually printed. Even if the letters were based on some kind of digital logo or typeface, the signs themselves were hand-painted on wood.
