Not sure how well this would work in the real world, but we do like the thought process. The In-Lock is designed to create secure storage for your bike when camping, or anytime you run out of street signs and lamp posts to chain your trusted steed to. Twist the corkscrew into the ground (using the provide bar), slip a chain through the eye. (see 'how-to' image after the fold) The blades of the corkscrew are wide enough to resist pulling up through soil. There are numerous ways the lock could be thwarted by determined thieves, but against the casual, light-fingered person it would have some useful deterrent value. Regardless of actual effectiveness, we applaud any move to make cycling a more positive experience. In-Lock concept by John Wrightson, via Cool Hunter.
