Wow, the new 'Manual on Uniform Traffic Control Devices' [for streets and highways] 2009 Edition, has really opened my eyes! What a difference more than 15 years makes! Anyone interested in changing/challenging their local traffic control setups should peruse this manual (the bible, so to speak) and any or all local supplements to above said document. It is the basis for setting up your systems, and I do not doubt there are many provisions allowing variances all across the US. I have @ 16+ years and 27+ meg of reading to catch up on.

No time like the present!
