It's a good thing.

Man it's such a good thing i saw this sign! cuz i saw some nice jaggedy rocks right below the bridge and i was like "Man, wouldnt' that be fun to jump onto?" But thank god i saw this sign and was informed that jumping from bridges and cliffs not only can, but HAVE resulted in injury and death!!! I mean, who woulda thought?? I guess it makes sense if you really think about it though.

Well that was a truly life changing experiece. I'll never jump off a bridge or cliff again!
