Balsa wood lumber in New England

Does anyone know of a supplier of Balsa wood lumber in New England/Rhode Island area? All I can find are 36" long pieces.

Have you talked to National Balsa?

They sell 48" stuff, not that that’s much better. Maybe if you pick it up instead of having it shipped they’d sell you longer stuff. They’re in Monson, MA, inbetween Springfield and Worcester roughly.
