The cache is at the crossroads of two highways that can take you to Martinsville, Spencer, or Cloverdale. These are heavily traveled highways by cars and semis alike. There are no Interstates close by, so it is the fastest way to travel through the area.
A gas station is lucky to be positioned here and gets a lot of business from all the people passing by. There isnt another gas station for miles in any direction. This is not one of those 24 hour gas stations. It closes generally by about 8:30pm so not too much worry about muggles after it closes.
