When I announced that I had created a way to save the plans I create for my bike tours and to make them public (announced in this thread), someone expressed concern that putting such "details" on the internet would lead to people lying in wait for me by the side of the road and/or people locating my house and breaking in while I was away.
I realize my experience is only one data point, but after listing my bike touring plans for the world to see, no one jumped out of the bushes and stole my gear, robbed me, threatened me in any way, or found out where I live and broke into my house.
Further, the links I put on-line came in handy many times while I was on the road and needed to refer to things I'd stored there. The best part, though, is that this information is now available to anyone else who might be planning a bike trip in the UK.
I fully intend to continue doing my planning this way and hope that people will join me in creating yet more resources for the bike touring community.
