Thanks for this message, Kurt.
I saw an incredible number of 30A stickers on 395 for the first time on Sunday. IMO people shouldn't put stickers on government-owned property such as street signs, or any property without the owner's permission. Some of the road signs on 395 are so covered with 30A stickers that they are unreadable and will probably have to be replaced.
Yes, I did photograph a SoWal sticker on one of the harbour boats in Sydney in July with the Sydney Opera House in the background. But I took it off immediately after taking the photo. Ditto for the Bruno's sticker I took a photo of.
