Oceanside, OR is about 10 miles north of Tillamook and my family and I went agate hunting and happened upon MANY pieces of sea glass that day! I found about 7 pieces myself, and my brothers each found at least 3 each! (I have 2 other brothers that were looking). I found a star shaped piece that's clear with a green strip of glass in the middle that I believe was a beaded necklace or bracelet. I would rate this beach at least at fair, and maybe even good or excellent, considering how much we found that day! I think we were there just after a good storm and as the tide was going out, so we were there at a great time!
