haha nice "555"
they are some good points you brought up.
i think it is more so for some one who rides a bike to the beach, and i guess you would just leave it assembled.
as for the locking up...thats a good one but, i would just use my bike lock.
you definetly raise a few possible downsides to using the "quiverkaddy"
though, im sure there are ways around it, otherwise it wouldnt have been built.
