Today I am selling the coordinates to a TRIPLE Cave Spider Farm, smp3,there are 3 spawners in the range of an AFK player that will spawn cave spiders, the area is safe and is already setup in a system that kills the spiders automatically and puts the string into a chest - this setup can be changed though if you'd like to kill the spiders for AFK.I have a nether rail that goes right to the base where the spawners are located, it is about 2000 blocks long on the rail. At the moment it is setup for auto-kill AFK string farming. I have gotten 10+ DCs of string from this farm. If you are interested in this farm let me know in a PM.I am looking for 70,000r but the price is negotiable.http://empireminecraft.com/threads/guide-selling-mob-spawner-locations.9738/
