A wet "Warning Sign"

Contribution by Shawn, quote:
I took this picture outside of a fast food restaurant while on our way to a TN/Bama football game in Oct 2004. The obvious part that strikes me the most is the "It's just water". In my opinion, this is there to warn me in case I see this big tank leaking in the parking lot or dripping all over my car while driving down the road, that it's "okay"...because it's just "water". I guess I would get excited if it said something like "Toxic Waste, Stay Back".
