Thanks, telescooper, They switched operators on the machine I was assigned to. I ran 8 loads to him and didn't have a problem all night. Now that I've been on this job a few weeks, the other drivers are starting to share info. Apparently, the 1st operator was taken off the machine because he had a problem keeping his car out of bars before work.....Shoulders are done, on to milling and binder for the traffic lanes...Thanks for all the help and advice!
