I have a question relating to #2. I found out recently that the DOT in Alabama (not sure if it's OSHA too) has changed its required vests for road crews from orange to neon green. A civil engineer and I have speculated that they probably found that orange vests were too similar to other construction orange cones, barriers, etc.

Are you guys wearing prodominately orange or green vests? Is the green easier to see at night?
