You can change your tent - -
Or you can change how you think.
The chances of getting your bike stolen in remote locations are - remote.
What is the value of being free from worry on a tour?
I have twenty years of touring experience and have rarely even locked my bike.
And I have spent the night from the Arizona deserts to the Northwest Territories.
You will never get a tent big enough to contain all possible worries.
But it is possible to leave the worries behind at the beginning of a tour.
