loking for wood
keep an eye out for asphlund cutting trees on the side of the road . they leave it where it falls , ask the land owner before you take though . look for saw mills in your area they usually give the slabs away . also try the local lumber yards .I know the local Whipple's lumber yard will give away all the cutoff's (small pieces of wood) sometimes if you are located close enough they will evan deliver it for free. since you have a out door unit you can burn pine also look for a local pallet manufacture they would give the wood they cannot use away ,
good luck
