for me

 

it would have to be things to survive on land

 

ive never hunted or skinned what was shot or set it up for preservation

 

land navigation i know

 

basically how to live off the land

 

build shelters on land

 

fire making at its most primative

 

how to track prey

 

my home was the sea

 

so about anything that has to do with surviving on land
