I find that they put holes in my plastic clothing, sleeping bags, tents, etc. which does excite me greatly.
Big bonfires are a major social event where we live so I always wear cotton-based clothes like Carhartt to those now.
Just finished building an outdoor shower from cedar and mahogany (for the deck). Have lots of cedar scraps (and just a little mahogany) left over...threw some in a fireplace fire this weekend...yes, it does pop!
