I have a raster and would like to recode everything in classes 2-20 to class 1. It is a mask that goes over a satellite image to hide the clouds. So everything should be either class 0 or class 1. It's easy to do this in ERDAS  Imagine with the raster recode but I can't figure out how to do it in ArcGIS. Does anyone know how?
