Sounds to me like a route would have two belongs_to, one for the start
and one for the end. Another way (which may or may not be relevant)
would be for routes to has_many locations through waypoints: the join
table would have a column specifying the order and would define the
locations through which the route passes (of which start and end are
just special cases)
