Thank you, Mr. Chair. There is no special requirement for engineers to always have a buddy, but it would depend on the particular circumstances, situation. A lot of times it is a safer situation if there are two individuals in the vehicle driving long distances. Sometimes the requirements of the job will take two people as well if you're out inspection or doing a job. There is no special requirement that there has to be two people. It's just the way it would work out and I'm sure that there are many times that we would send one person out in a vehicle as well. Thank you, Mr. Chair.
