I know of a few trees along paths in my regular hunting area that have been or are under constant attack by hungry Woodpeckers.
The holes bored by these relentless ravenous birds leak sugary drops of semi liquid crystals. These trees provide me with a fairly regular supply of Fat wood - Light wood -Splint wood - Candle wood or Pitch wood whatever you want to call it.....
It's fire on a stick!
A small handful of pine pitch or fat wood should find it's way into your fire kit. When it's wet outside and you need to start that camp fire, nothing aids you as well as this natural resin for your fire. With perhaps some Birch bark to set it off, a handful of resin will burn hot and long enough to give an even damp fire set a good chance at life.
