Thanks for writing this letter.

There are a two additional comments to make.

1. Here is a link to the CRS 42-4-1412: http://www.michie.com/colorado/lpext...templates&2.0#
Note that the sheriff has by omission skipped over conditions whereby provisions for riding as far right as practicable
do not apply such as preparing to make a left turn or avoiding debris. If he is going to try quoting the law, he shouldn't
just pick and choose to make his point.

2. If you haven't found it yet, one of the interesting resources is Bob Mionske in his books and articles.
