Question: The 12 hours it takes for the drivers to get to the garage - is that applicable to only the first time we mobilize them, or, if they go home, and come back for a second shift, are we looking at a 24 hour, 12 hour, or other time frame for their turnaround? Answer: Assume that once you "release" a crew from their responsibilites, it will take 12 hours to get them "prepped" for the next go. I believe there's something about this in the Seattle/Snowplow Operators Union agreement. Ask Homer Simpson about it, he should know.
