I switched to burning Poplar now mostly to get rid of it and cuz it's so mild out. I don't go out of my way to find it but do cull sick trees on my land. Anyway, what I brought in tonight was discoloured and I noticed an off smell as I was re-splitting it in the shed to bring in. Now it stunk up my whole house with the smell of sour milk and rotten fruit. I don't feel like taking it back outside and it's too much to stuff into the stove since it's so mild out. Oh crap.
