Not really.  A foot is about a light-nanosecond, yes, but
high-frequency signals in copper travel by skin effect, moving
significantly more slowly - somewhere around .6c, I think it is.

It's still on the general order of c, mind you; for the purposes of
this discussion, c and .5c - even .1c - are much the same.
