Thank you government! I could have sworn, I was driving on the Autobahn, without your warning. By the way, the sign is about 1 mile (1.6 km) from the beginning of the (same quality) road :-). Anyway, we're off to Kekaha Kai State Beach Park, but... ooops, there's another interesting sign too!
If you drive faster than 5 mph (8 km/h), you wreck your car, your brain, your butt... your kidney stones might improve though :-). The good news is, you don't really need a 4X4, it's mostly solid ground, minus a little gravel, here and there.
CAT# 16/1, 17/1
