title: Google Maps Direction Radius
body: <p>Using google maps v3 I can get directions from one marker to another but is there anyway to figure out other markers that are a max distance from the route I will travel</p>
  
  <p>Example:</p>
  
  <p>Say I am going form my house(start marker) to a friends house(end marker) and want to go to a gas station on the way (which will also have markers on map). Is there any way to figure out what gas stations are at most 2 miles off the path from my house to my friends?</p>
