We find strong evidence that both b and r change with scale for our sample of lens galaxies (19.5<R_C<21), which have luminosities around L_*. For the currently favored cosmology (\\Omega_m=0.3,\\Omega_\\Lambda=0.7), we find b=0.71^+0.06_-0.04 on a scale of 1-2 Mpc, increasing to ~1 on larger scales.
