i have an idea but was wondering if any one could show me pictures of the difference in aspen and cotton wood from the outside. also which one would be easier/faster to season and which one would burn better. i think i have an abundance of both but was wondering which one i should spend my time to cut and split. i dont care if it burns worse than oak because im sure some one will start that argument but oak doesnt "grow on trees" around here and i have a lot of these (i think)
