Actually, there are two towers very close to one another on Suavie Island, and the third tower that shows up on that map is in the field right behind Skyline School.Example of cell phone towers from NW Logie Trail Rd., note that #2 is on SI and if you click on it, you'll see it's near NW Reeder Rd.
