Hi Oli ....
a good way it is to go back to the roots !!!! :P
I like the way you travel !!
I did it the same way very often ... because when you get out on a small station somewhere on the country side, you easily find a place in nature to sleep ... or maybe even an camping are (to have some showers!)
I often sleept on a meadow somewhere and sometimes I met in the morning a nice farmer who asked me about my travel, gave me some milk ... nice person often when you are fare away from everything !!!
also if you go to camping areas near the big cities or even inside of cities, there are a lot of people out of money living there and you have to pay attention that nothing get stolen !!!
That's my experience ....
I wish you a lot of fun !!
