In the next few month you will begin to hear more discussion about sidewalks.  Most of the discussion will focus on the best locations for sidewalk and how they can be paid for.  A good way to review sidewalk options is to visit a site called www.walkable.org.  This site, operated by Mr. Dan Burden, is a national recognized site for sidewalk discussion.  The site has many pictures and articles.  Take some time to review the site and be prepare to participate in this discussion.
