Oh I love this question. I have lived in Mukilteo, since 1987. It is the most centrally located community on the map. I can be in Everett, Bellevue, or Downtown Seattle within 30 minutes. Ok, not in peak traffic times, but during many times of the day..I do a considerable amount of business downtown. We are near several transportation hubs and the Sounder train has just begun service to downtown. You ask the eastside vs the westside. Well, I am a west side advocate, and unashamed to tell people so. Remember there is only so much room between 1-5 and the water. Everyone east has to come west to get to I-5. Thats a lot of land, and more traffic lights than you want to work your way through. Besides the sun always sets on the west..
