If you're bike touring and planning on sleeping in a tent, how do you make sure your bike does not get stolen from the camp ground when you're asleep? I doubt you would be able to fit the bike inside the tent with you. This might be a silly question, but it's a thought that came to my mind..
dittoJust use a cable lock and lock it to the nearest tree, fence, lamp post, or whatever.
Most campsites are pretty safe.
In 30 years of cycle touring, involving hundreds of nights camping in various countries, nothing untoward has happened to my bike on a campsite.
