Yes, its like that really long haylike brown grass/weed that collects up in big mounds on the beach, I think I've seen it in your beach photos, the puritans called it 'salt hay' so we new englanders still do. Just get armload fulls. It's great mulch as it keeps it moist and when it breaks down makes great soil. When I pick mine up I always get tons of sand fleas jumping, but I mean they can't hurt you, just annoy you and an unfortunate name :) Now get your wellies on and go harvest your salt hay then I'll met you down cellar for a chin-wag and a cuppa. How's that?
