As this is my first post I thought to be upbeat.
I have just returned from Ontario Canada and have had a marvellous cycling experience. Living in Scotland as I do I can tell you that the courtesy and consideration I experienced in Canada from both trucks and light vehicles was awesome. They went out of their way to give me a wide berth and I can state that having a truck pass me without feeling the "suction" effect was a truly enjoyable experience.
I take off my hat to the good drivers who made my visit truly memorable by being so very polite to a rather nervous "on the wrong side of the road" cyclist.
