Still not clear if I can make it that weekend so another question mark for your excel sheet Jurjen...
If I am coming I´ll be bringing along some homemade firepistons (including the knowledge to make one yourself), some bamboo for firesawing, some rattan for the fire thong (I have never succeeded with it but is fun to try) and a special piece of bamboo that produces sparks with flint. I can do a workshop as well on those four SouthEast Asian firestarting methods. I´ll probably also have some ´chaga´ (Inonotus obliquus) and cramp ball fungus (Daldinia concentrica) with me to play with.
PS Although I´m not sure if I´ll be there, I´m already claiming 2 trees for my hammock
I always carry my tinder in my bellybutton...
