The expression, “If it ain’t broke, don’t fix it,” refers to the idea that any attempt to improve something that already works well is pointless and may even be detrimental.

These drop-offs develop as the material adjacent to the pavement settles, erodes, or is worn away. A pavement edge drop-off can create problems after a vehicle driver drifts off the pa...... continue reading

Most anyone living in Ohio—will quickly correct the mistake, if it’s made. And don’t forget the word “the” in front of Ohio State University. It is The Ohio State University (although curiously, it is referred to as OSU, not The OSU). Founded in 1870, OSU is the second-largest university campus in the US and is one of only a few universities to have both a department ...... continue reading
