  We study a class of ``landscape'' models in which all vacua have positive
energy density, so that inflation never ends and bubbles of different vacua are
endlessly ``recycled''. In such models, each geodesic observer passes through
an infinite sequence of bubbles, visiting all possible kinds of vacua. The
bubble abundance $p_j$ can then be defined as the frequency at which bubbles of
type $j$ are visited along the worldline of an observer. We compare this
definition with the recently proposed general prescription for $p_j$ and show
that they give identical results.
