Your Favorite Bike Parking

Those basic wiggle racks are generally quite utilitarian, although it is not uncommon for a person to park sideways, taking up spots for 3 or 4 bikes.

I have to agree with DiabloScott, the slinky rack looks cute, but isn't very utilitarian.

One of my favorite racks is actually the swinging racks at Walmart. Unfortunately I don't think I have any photos. I'll try to get a photo soon. They don't take up much space when not in use. They securely grab a tire, and provide a place to catch the lock.
