Here's the first line from my original post below:
"I can't take credit for this idea--I read it somewhere else--but it's so good that it needs to be promoted and publicized until Metro takes notice and implements it."That was August 30, 2008, 38 months ago. I'm glad to see it finally happened, but it's a bit discouraging to see that a no-brainer idea like this one can take so long. Imagine how long something expensive or contentious would take.
For history buffs, here's a comprehensive listing of all my posts and some other relevant links.
