I casually observed three school markers of this type while on a motorcycle ride between Calmar and Tofield, Alberta. I like running across these. I would like to know why someone decided to mark where schools once stood. It is an interesting project to undertake. I am also curious as to why there are so many different styles of school markers. I have found that some of these were purely locat, some were done through government funds, some were partnerships through local, government, and corporate groups which likely explains the variety.
