back in v12 i built a small air base on the slopes in the middle of the big lake, it was a decent build for a noob like me, it had a basement and a 2nd flight deck below the first, the whole thing only launched flying wheeled jeeps and i spent hours trying to land one on the base again, I never could. I did rebuild it in 2011 with some major improvements and hosted a server for about a week or two but it sucked.
I miss those days, and plus both save files are on my computer that doesnt work anymore. I could extract them if I wanted to, but of course slopes died a peaceful death before I could ever do that
