I live in Kincora and work in Quarry Park. Try to leave between 6:15 and 6:30 in the morning. Every 15 min makes a difference in terms of traffic. I don't know how people can drive between 7 and 8. I would go postal.
Going to work can be 20 min on a good day, and 40 on heavy days. With accident it can be an hour.
Looks like we might be moving to the DT office. If bus is 30 min I can handle. Years ago when I bus from Sandstone at 7 I would not get a seat. Might be seats when I get on but after the bus is filled seat would be given up to elderly, women, etc.
