  :A good intent could be maintaining being concise without being loose; some polishing of wording could help.  A few yards is still within the right-of-way (which is not particulary wide) and so is sufficiently close that meaningful accuracy is not lost; such changes are not extensive with respect to the entire length.  Most changes are so small that they are barely detectable, if at all, on route maps.  Releveant points are that the line was converted to another active use, the new use essentially follows the original line, the changeover has been gradual (the first segment of the B-G was nominal), and the new use is being integrated into a larger, comprehensive system.  Further detail could be made available with an appropriate reference to the Burke-Gilman Trail or SLS&E; articles.  (A map being needed is noted at SLS&E;, the B-G Trail article has detailed links to detailed maps.)
