Optical/near-IR surveys for galaxy clusters have undergone a resurgence in the past few years, thanks to the development of
large-format imaging cameras on large telescopes and the development of elaborate cluster-finding algorithms to analyze the resulting deep
galaxy catalogs.
In this talk I will discuss recent results from one of the largest existing optical cluster survey projects - the Red-Sequence Cluster Surveys(RCS-1/2), including the development of several instruments designed to enable large follow-up programs. I will show a sequence of results from RCS-1 covering a range detailed analyses of particular clusters to statistical analyses of evolutionary trends revealed by the survey sample as a whole. Time premitting, I will illustrate how the 10x bigger RCS-2 project, which is now nearing completion, will expand and refine these results.
