This is the address of a web page on the internet. Each page on the internet has an address. There are two kinds of links on a web page. Internal links are places on a page that you click on that take you to another place on that one page. If you click on it you will go back to the top of this page.
External links are a little different .
If you click on an external link you will end up on a new web page. Be as specific as you can. My first step would be to see if Yahoo has any information on this topic. Click on the Yahoo link on this page. Type in Shenandoah Valley to do a search within Yahoo.
