Now I'm ready. It took me all damn evening to do it, but I finally am convinced that I have the right number for my lunitidal interval for my 7900 coming in tomorrow and a GLX5600 that is making its way here at a more leisurely pace. Seattle and Los Angeles just didn't seem similar enough for the their numbers to work for the beaches closest to Portland and their numbers differ by a good margin anyway. In my quest I finally found two websites that will actually identify the cities along the Oregon coast that don't make the cut for most major sites that provide tide calendars and and moon intervals. As a bonus I actually even spent part of the evening learning how to calculate lunitidal intervals from some dude from what I imagine must be Scotland on YouTube with a pretty pronounced accent. If anyone else needs the links, give me a shout.
