"Typical concerns have centered on trees and motorists using local roads as a detour"

From today's World Wide Words, ed. M. Quinion:

"The Daily Herald of Arlington Heights, Illinois, had a story on 10
June about road construction:

"Typical concerns have centered on
trees and motorists using local roads as a detour."

"Edward Floden
remarked, "As everyone knows, trees are poor drivers and move too
slowly.""
