I learned a lot from installing my chimney liner with Hogwildz, about what the inside of my chimney looks like, how liners work, etc. etc. And now I can burn safely! What I also learned is, sometime's it's better to hire stuff done. I'm missing one arm and the other is held together with screws- not the best ingredients for lifting weight over your head. Took my first sick day in 5 years to take Aleve and feel sorry for myself. Ugh.
