The fishing store on Louisiana Avenue across from the golf course is still open, but odd hours. Like swampman says, Hebert's in Henderson has them. Also if you're going to Chicot, Industrial Supply in Ville Platt has them as well.

Tal, that store in Carencro no longer sells ethanol free gas like they used to. You'll have to go to the Chevron on Gloria Switch down from your clinic for some.
