Tracing the  cosmic evolution  of the Baryonic  Acoustic Oscillation (BAO) scale with galaxy two point correlation functions is currently the most promising approach to detect dark energy at early times.  A number of ongoing  and future experiments will measure the BAO peak with unprecedented accuracy.  N-body simulations indicate that the matter distribution  is  anisotropic out  to ~150 Mpc, far beyond the  BAO scale  of about 100 Mpc. I will discuss implications for the measurement of the BAO.
