Believe it or not I've never been to the nether. I backed up my world before going in so I've not lost anything but no matter where I place the portal in the over-world I come out with barely any or no "ground to stand on, I seem to always come out on a floating island of netherrack above a lava lake. When I do have a spot to walk on it's quickly blown out from under my by ghasts. Either I just have really crappy luck with this or there's a trick to this that I don't know of. Any suggestions? I'd rather not have to put my main nether portal a long distance from my home.
