Walked along both sides of the river and "spammed" (is it spam if it's a good thing?) it with 7 stickers. I had more on me but only wanted to place them at locations that get lots of foot traffic.

Nicely done, just zapped you for all 7!
In the future try not to put stickers on porous surfaces like concrete since it will likely come off in the rain. Stick to metal, glass, or plastic :)
Most stone surfaces were polished smooth so rain shouldn't be an issue. With thebgiant stone with the fish being the exception.
