If you use Warmshowers or hostels you are almost forced to be "social". I also find that the same goes for when you use campsites
as it's easy to strike up conversations with the folks next door and share a beer or some food. Also if you tour on a popular route
there will be lots of fellow tourers to talk to and ride with on sections. I found riding the NT to be very social as I did sections with
a couple of other cyclists and stayed with Warmshowers hosts quite often.
