Getting Home - Odd thought

[Sunna]

as I often sleep in my truck I have a good lot of stuff to use plus food and water meds for general stuff a first aid kit tools knives ect.
draw back I could be 100s of miles from home , Friday I was in linconshire that place is flat and empty several fields between homes and farms getting back from their would be hard , but better than London and the south east.

how would I do it , walk , bike [sore ass] for me the hardest thing would to know where your going , you would need roads for general direction , train tracks , rivers , nr said about following power lines good idea but where do they go...?
