For those who like to pursue bivalves, here is a little easier to read tide guide. It takes a standard tide guide and strips it of info not needed for bivalve digging (most of it). The info that is left is ranked on both the height of the tide and the time of day that it occurs (tides at night rank lower than tides during the day). It's good for looking at large periods of time very quickly.
