  We investigate the dependence of solar wind fluctuations measured by the Wind
spacecraft on scale and on the degree of alignment between oppositely directed
Elsasser fields. This alignment controls the strength of the non-linear
interactions and, therefore, the turbulence. We find that at scales larger than
the outer scale of the turbulence the Elsasser fluctuations become on average
more anti-aligned as the outer scale is approached from above. Conditioning
structure functions using the alignment angle reveals turbulent scaling of
unaligned fluctuations at scales previously believed to lie outside the
turbulent cascade in the `1/f range'. We argue that the 1/f range contains a
mixture of non-interacting anti-aligned population of Alfv\'{e}n waves and
magnetic force-free structures plus a subdominant population of unaligned
cascading turbulent fluctuations.
