The Red-Sequence Cluster Survey (RCS) is a 100 square degree galaxy cluster survey designed to provide a large sample of optically selected clusters of galaxies with redshifts 0.11/2= 111+-5 km/s. In addition we have constrained for the first time the extent of dark matter halos, and find a robust upper limit for the truncation parameter s<470 h-1 kpc (99.7% confidence). A preliminary analysis also excludes a simple ``prediction'' of lensing according to Modified Newtonian Dynamics (MOND) at high confidence.
