[HamWAN PSDR] Coverage Question

Hi There, I am currently researching how best to use my recently gained General license. I live at 7510 Sunset Dr, Blaine WA (actually in Birch bay) and your coverage map looks encouraging. I have easy access to my roof (Widow's Walk) on my 3-story house so can get some height for Ae installation. I am also about to join PNWDigital.net as I have a DRM Anytone D578. I am part a patriot/ham group in the Sedro Wooley/Mount Vernon area and we are looking at ways to keep in touch by radio and gain internet access in an emergency. This all looks promising to me.
