I put an ad on Denver Free cycle for the remaining pieces of the tree.  Free Cycle is a yahoo user group for people giving away stuff, like free fire wood.  I also put it on the Denver user group at work. I told the I had cut down a tree and was giving away the wood as firewood.  I included a picture.

 I then got the most ridiculous questions.  People want to know if the wood was seasoned.  It just got cut down!  People commented it was to big for there fireplaces.  They didn't own axes to split it! How can you have fireplace and not have an ax or hatchet?
