  We construct a toy a model which demonstrates that large field single scalar
inflation can produce an arbitrarily small scalar to tensor ratio in the window
of e-foldings recoverable from CMB experiments. This is done by generalizing
the $\alpha$-attractor models to allow the potential to approach a constant as
rapidly as we desire for super-planckian field values. This implies that a
non-detection of r alone can never rule out entirely the theory of large field
inflation.
