Gift/sell "Fish Don't leave Footprints" achieve

to be able to gift the achievement Fish don't leave footprints you all you need is a single point in fishing!
go to the wetlands and look for schooner wreckage try around the lake to the south.

Watertight Trunk - Item - World of Warcraft

the item that gives the achievement is a 7% drop rate from those crates.

the trick is to not have the achievement on the character you farm it on so you can see it in the chest.
open but do not loot the chest and look inside for the "Weather-Beaten Journal" from the schooner wreckage.
you'll be able to trade it to a friend/ or buyer and they'll earn the achievement if it has the "Weather-Beaten Journal"

cheers!
