Please don't blast me, this isn't meant as an attack of any kind, just information- but it is not "Darians" or "Dariens" gap...
The Darien Gap, (with one of those little apostrophe things on the e, (I don't know how to do that...)), is a jungle and marshland area between Panama and Colombia.
From what I've heard, AKBB's cross leans more towards the Panamanian side of things in terms of terps.
Snowhigh has said strains from these areas can sometimes have sharp barbs on the roots... as a form of protection I guess.
