I believe marking the arrows at the Kailua Shopping Area is a fantastic idea. I noticed the parking lot by So Kailua, just got a make over yesterday...(I'd bet that it'll be done before Saturday)

Last week while pulling into a stall at times, I noticed a convertible with some Japanese tourist going in the wrong direction. I got their attention, and tried to use sign language to let them know that they were going the wrong direction.
We made progress, and they were able to drive into an empty stall and turn around so that they would be facing in the right direction.

Never received a ticket from the Times or Foodland Parking Lot, but have seen the attendants who issue them walking around and marking tires.

Received a Ticket at Cinnamons Parking Lot...fine 35.00...
Beats the towing expenses, that's for sure.
