airports:
- 
  name: 'La Crosse, WI'
  code: LSE
  directions: http://g.co/maps/62ufz
  image: 'lacrosse-image.jpg'
  website: http://www.cityoflacrosse.org/index.aspx?NID=851
  rental_cars: http://www.cityoflacrosse.org/index.aspx?NID=882
  description: La Crosse is the closest flight destination. It is right 
    on the Mississippi and about an hour away. It is a small airport so we 
    <strong>definitely recommend</strong> making a rental car reservation ahead of time.
-
  name: 'Madison, WI'
  code: MSN
  directions: http://g.co/maps/sghms 
  image: madison-image.jpg
  website: http://www.msnairport.com/
  rental_cars: http://msnairport.com/guide/car_rental.aspx
  description: You also can fly into Madison and drive through the gorgeous 
    countryside. Flying into Madison often saves you $50 (over La Crosse), however,
    you now have a two-and-half hour drive.
-
  name: 'Minneapolis, WI'
  code: MSP
  directions: http://g.co/maps/tk827
  image: minneapolis-image.jpg
  website: http://msairport.com/

  description: Another option is to drive three hours from the Minneapolis airport. 
    Flying into here will often save you $50 (over La Crosse).
