Hi if you're going to spain....
check out the prickly pears, they grow there like weeds!
if you can get into them they are very tasty!
(i suggest leather gloves and a sharp knife!)
other bushcrafty stuff you could try,
you may come across almond, orange, olive, and ucalyptus trees!
i saw evidence of wild boar and a huge snakes skull (skeleton) the size of my fist!
i haven't been doing any bushcraft myself over the last while, just trying to set up some local enviromental work.
though i've come across (or have i invented it???) a very fast guy rope system to tie tarps to trees!
also a hoop pole design to change any rectangular (or square) tarp into a small hoop tent, with one pole and 6 pegs!
i feel a demo is in order!
I'll need to take some photo's.
also i took a walk in the attlebridge area (near horsford)and found a great unspoilt woodland sadly it's private, but well worth a look!
