This is smart: the In-Lock is a bike lock for use at campsites and other outdoor places that lack anythng handy to lock your bike to. It's got a long steel screw that you drive into the ground with a turning bar; once you've locked your bike to the screw, you can't use the bar to un-turn the screw. It's just a prototype for now, but it looks like it'd work a treat.

Update: Colin sez,
The makers of the In-Lock make some pretty bold claims. First of all, the stake looks like it is less than 12 inches long with screw threads that are only about 3 inches in diameter. It really would not take much effort to overcome the "physics" that they claim secures into the ground. Along those same lines, they claim that "physics" prevents the screw from being turned because a chain runs through the stake. Well, this would only be true if your chain were either extremely stiff or so short that the stake was right up against the bike wheel. Otherwise, you could certainly turn the stake at least 180 degrees in either direction, more than enough to get you started in championing their indominatable "physics".
Update 2 David sez, "How it should work: The bar you use for leverage to put the screw in the ground should also be a stake. After putting in the screw, you put the stake through a hole on the side of the screw's head and into the ground, then lock the stake in place (relative to the screw) with a regular lock."
Update 3: Phil sez, "Have two of those suckers. Screw them into the ground 2 feet apart,
with the open eyes facing each other. Run a 3-foot long eyebolt
through both eyes; padlock the eyebolt to one of the eyes so that
the bolt is now locked through both anchors and can't be removed.
Lock bikes anywhere along the eyebolt between the anchors. With the eyebolt through both anchors, neither one will turn."
