I became fascinated with beach glass (I refuse to call it 'sea glass') when I was a kid, and have been collecting it for as long as I can remember. You don't see a lot of beach glass anymore since most bottles are recycled. And out here the Pacific pounds things to bits. I used to have fairly good luck in the 70's and 80's on the Cape beaches, and then at Glass Beach in Fort Bragg, California, where I got most of my best finds including interesting shells, shards of pottery, china & ceramic, and the rarest of all: Red. Cobalt is hard to find too.
When I was little and would play by myself at Spring Hill, I would fantasize that, as I was climbing over the jetties, there would be a huge pile of beach glass treasure on the other side of the breakwater. Of course there never was, but I still remember that anticipation of hoping to find treasure on the other side. I dream about beachcombing a lot.
