Locate a sign that displays an important, life-preserving message.
Each posted sign represents a person that died because the person was unwilling or did not understand the dangers mentioned on the sign.
To validate your find :
You need to post in your log a picture showing "Danger: Swift Water" panel WITH YOUR USERNAME VISIBLE, CLEAR AND READABLE written on the medium of your choice (paper, hand, phone, t-shirt, etc...).
Pictures taken with only yourself, your GPS or your Logo/Avatar are not accepted as well as photoshopped/edited pictures with your username inserted afterward.
Failure to follow these instructions will lead to your log deleted.
