I have a double spawner to get rid of as I am just bored with it. It made need to be re-worked as I am not a pro at it. The spawners are 5 blocks diagonal apart and I am leaving all my stuff there too. There are pics included. If you have any questions let me know. Make me an offer.
It's a zombie grinder but like I stated in the forums..I'm no pro at it. It is on SMP7 and pretty far out but there is a nether portal to it. The zom cages are 6 blocks apart and in the same enclosure if that helps explain any better. I have used it often and it goes really well. By the time I have done a few things above it (gardening, smelting etc.) it has built up pretty good. Someone my consider tweaking it though.
I just got tired of messing with it to be honest. Took the pics I could and left. It's actually about 4000 out...I just went to 7 to see. The nether part of it I only used leaving...always died to get back.
Misa'a...but it's not completely updated. Some of the newer flowers are default. I just like it so much that I deal with it.
