You would think that any signpost should be clear and unambiguous....think again, this one I spotted today got me wondering about the meaning, did it mean:

1) A zone around the school where one could obtain free drugs?
2) A zone where schools cerified free of drugs were collected?
3) A drug for free schools in a particular defined area?

I finally settled on what I thought was the most likely meaning, an expectation that the zone around the school should be free of drugs...but then I wondered to what purpose....did the people who put the sign up think it would deter drug dealers???

I really must stop looking at signs...I clearly can't grasp their purpose or meaning....
