Ok startrd to check and see if my hard paid off. Trying to level out my site. Pounded a stake in the middle ran a screaw in it tied string. Got a deck rail wood spindle {1 1/2 x 1 1/2} tied other end of string to that and took a 5" x 8 ' board and screawed it to the bottom of wood spindle. This is where I am having the brain fart to find the low spot the lowest part of the surface the string will be at it's bottom point on the spindle correct? Plan on digging the middle out so is it ok just to worry about the bottom rail and post supports for the most level ground or does the whole thing need to be level?
