Like many here, I would prefer to ride with soft panniers over hard boxes but my biggest concern is theft. I often don't have a choice where I park and often (I realize my riding style is rare for 1st world countries) I NEED to ride dirt single track and city traffic and park in less than desire places and be out of view of my bike for a couple hours. It's occured to me that my biggest hold up with soft panniers is fear of theft. At the same time, the reality is I know that it is pretty darn easy to force the locks on my hard panniers open AND hundreds of times I've accidently forgot to lock them. It's been a long time since anything has been stolen... I'm just curious what your stories are? Examples of NOT getting something stolen when you thought you would/should or getting stuff stolen despite all the precautions?
