There are many ways to lock your bike up, but like tight jeans or a crop shirt, just because you can do something (or wear something), does not mean you should.
Reader John from Northern Idaho sent the following text and pictures:
I spotted this interesting lock job at a bike rack outside the main entrance of a Safeway grocery store in northern Idaho. This person locks their bike to one bar of the rack with a keyed padlock around one spoke. I have included a photo of the bike and rack and a photo of a close-up showing the lock around the one spoke.
Of course if you live in a small enough town, maybe this is good enough.
And it's a quick release to boot.
