Lin,
I am certain we'll hear from someone about this, but I drilled an access hole in the support piece of the boot right over the " hard to get at " location. After that, it is no trouble fastening down the script. With only two fastened down, the unfastened edge turns up a little and then you'll snag your washing or waxing cloth on the edge. This doesn't happen as easy with all three firmly attached.
