You're going to look pretty silly climbing up onto that billboard with your cellphone.
I don't know if a QR code would be much better.
Recently I was at a music festival where they had some type of QR code hunt going on.
The codes were all behind the fences where drunk people couldn't reach and destroy them, and just that bit of distance made it quite difficult to read the codes, even outside on a cloudy day (the abundant difuse light should be perfect for this).
Granted the codes they were using were a lot denser than needed (they were embedding the clue to the next code in English and German in the code itself -- stupid since you were using the festival's app to read the code anyway, they could've embedded the text in the app itself), which made them harder to read than normal, but the code was also quite big.
I also tried to read a small (unrelated) QR code which was glued to a pole, and the distortion caused by the pole's circumference made the code impossible to read.
So reading a code from a billboard, even in perfect conditions... It'd have to be pretty fucking huge!
