IMO, when dock conditions are so bad that it is nearly impossible to move, dock operations should be suspended. It is ridiculous to sit and watch 50 dock workers burning the sh1t out of the tires on forklifts trying to get out of trailers. The cost of lost productivity, accidents ( and possible lawsuits), forklift damage, freight dameage (How many drums get punctured when it's slick on the dock?).
I think I may have been in IND the day after the snow you were talking about. Of course I did not see the inside of the dock. That was kind of unusual for IND wasn't it.
