RE: moon overhead & moon underfoot
Overhead is when it is as high inthe sky as it can get, underfoot means it' s on the other side of the world. Wether you should hunt feeding areas or transition areas depends on the moon position. Overhead and underfoot are the same as for where you should hunt. and wether it is rising or falling will also describe the hunting area.
Solunar tables will describe major and minor feeding times yet not all deer will be as predictable as those tables, however fish will be.
