Goombay drums, along with medicinal herbs, calabash shells and abengs (cow horns), are for sale in the tiny red-and-green craft shop as you enter town. The hand-carved goombay drum (around J$4000) is box-shaped and covered with goat skin, while abengs (around J$3000), used by Maroons to signal rebellion, make a wonderfully deep and resonant racket.
Whoever is manning the museum next door can open the shop for you.
