I have the opportunity to get free fire wood,to burn...Being I live in the city,wood is tougher to come by without buying it...<br /><br />The wood is from a box elder tree, and also a willow tree.<br /><br />Im not very knowledgable about firewood,and such but was wondering if it was worth going to get and chop up.<br /><br />Now if it was oak,or cherry or another hardwood,it would be obvious but Im not sure if it would be worth my trouble.....<br />Any thoughts?
