Altogether a most enjoyable day, The ride was good, and it is surprising how car drivers behave when every other rider was a policeman on Police bikes wearing a yellow vest with POLICE all over the back of it. As an aside, I can assure you that British policemen are human aswell.
I was on the Trek Tri-Island ride in Washington State in 1996 and we had two police officers from Kirkland, Washington, along wearing their t-shirts with POLICE on the back. It certainly helped calm down so drivres who were not happy with all the cyclists on the roads.
