I have never locked my bike while on tour, however a recent experience has driven home the idea that maybe I should. While having coffee the other day in a coffee shop. I noticed someone steal my Surly LHT, I stopped the thief after he had ridden the bike maybe 10 feet after which he left hurriedly in a waiting car. ( I had his license plate number in this, a very long story ). The Police said little could be done. The reason for the post however is to ask what other tourists do to prevent a bike theft, when leaving a hotel on a walk through a local community, or possibly while taking bus tour to a local attraction away from your tent, or even while sleeping in your tent. For the later I've thought of a bell , as well as a string attached to the tent to provide some warning. Idea's ?
