I have a dynamic website which will have location-based internal pages that will have a <title>and <h1> title, and meta description tag that will include the subregion of a city.  Each page also will have an 'info' section describing the generic product/service offered which will also include the name of the subregion.  The 'specific product/service content will be dynamic but in some cases will be almost identical--ie subregion A may sometimes have the same specific content result as subregion B.  Will the difference of just the location put in each of the above tags be enough for me to avoid a Duplicate Content concern?</p></title>
