  A direction in a Type I space $X=\cup_{\alpha<\omega_1}X_\alpha$ is a closed
and unbounded subset $D$ of $X$ such that given any continuous
$f:X\to\mathbb{L}_{\ge 0}$ (the closed long ray), if $f$ is unbounded on $D$
then $f$ is unbounded on each unbounded subset of $D$. A closed copy of
$\omega_1$ is a direction in any Type I space. We study various aspects of
directions and show some independence results. A sample: There is an
$\omega$-bounded Type I space without direction; PFA implies that a locally
compact countably tight $\omega_1$-compact Type I space contains a direction;
if there is a Suslin tree then there is an $\omega_1$-compact Type I manifold
without direction; there are Type I first countable spaces which contain
directions and whose closed unbounded subsets contain each a closed unbounded
discrete subset. We also study a naturel order on the directions of a given
space and show that we may obtain various classical ordered types with the
space a manifold (often $\omega$-bounded).
