Great way to pass the time on road trips

So I love the outdoors and with that there's a lot of travel involved going to different locations for camping, fishing and hiking. Most of the time my sons wearing headphones and watching his own shows on his tablet, so I usually have the radio to myself and going through cities and states the radio stations change unless you use XM Satellite radio or Spotify. Lately I've been enjoying Audible books and it helps pass the time and I thought I'd pass it on. Thank You and check it out and get 2 free Audible books! Click the link and enjoy!
