There's so many programs worldwide to try and stop drinking & driving, there's even vending machines at clubs, restaurants etc here in our country. I'm sure it does reach some so really is worthwhile, your website sounds great, pity you had to stop but sure must have been time consuming as well, perhaps something you could do again when you retire? Will definitely look for your stickers online.
I know a couple who lost two children who were hit by a drunken driver whilst crossing the road, terrible tragedy!
Have a safe weekend mr Papper!
