In the mornings around here it's off Sandy Bay Road from 8.15 until 8.45 am or suffer the consequences - and it's not pretty place to be. The alternative route has a hill that is mountain bike granny all the way (not an option on a road bike) The decision makers have been trying to generate discussion on sorting this mess out but to no avail (NIMBY rules in Sandy Bay). Happiness would be school holdiays for 52 weeks a year - peak hour traffic drops by over a third during this time.
In the evenings/on the way home - high beam lights, especially from buses. I am seriously considering the acquisition of one intensely powerful spotlight to return the compliment to these people.
