We went camping last weekend up in Fort Bragg, about 2 1/2 hours north of where we live and we stopped at this beach. It's called glass beach, you can see why. There was no sand, just beach glass. We even dug down to see if we could get to sand, nope, just glass and some rocks with a few pieces of seaweed thrown in. It is seriously the coolest place I've ever been. I've never seen anything like it. It was wonderful. I can't wait to go back.
