Trader Joe's is the whole foods organic chain California. Dan rants about "dish rack" bike racks in use at a location in San Francisco. Readers comment with yawns and disinterest. Hat tip to Murph.
Some cities specify the type of bike racks that are permitted. The city of Denver, CO, for example, has an "equipment standard for bicycle parking areas" specifically spelling out inverted U bike racks as the preferred bike rack. The city of Palo Alto, CA, defines an "acceptable bicycle rack" as "a stationary object to which the bicycle user can lock the frame and one or both wheels of a bicycle with a user-provided high-security U shaped lock (“U-lock”) or cable, and which is either anchored to an immovable surface or is heavy enough that it cannot be easily moved."
