My bike is hidden inside my car and locked to a fold down rear seat back mount whenever I'm camping or at a motel.Some Guy said:I dont bother. I just make sure my bike isn't an attractive proposition for thievies.
I think some kind of a mantrap is in order. I suggest bring a rope and a string with you. Pull a nearby tree down to the ground securing it with a stick which can be easily slid out causing the tree to snap upright. Tie the rop off on the tip of the tree and then a large noose on the other end. Place the noose around your bike hiding it under leaves or loose dirt. Attach one end of the string to the bike and the other to the stick holding the tree down, hide the string like the rope. When somebody tries to take your bike, the string will release the tree and the noose will tighten around the legs of the thief pulling him up in the air and keeping him there (unless he has a knife) until you get back. Alternately dig and camouflage holes around your bike with poisoned bungee sticks implanted firmly in the bottom.Picard said:thanks for the tip derby. I never thought of it by locking to rear seat.
