I made the basic plan of a track a while ago and showed it to you, xpand.. I haven't done much work on it since. I finished the basic landscape but I haven't created any buildings even though it;s been so long; I'm guessing a combination of school (pointy end of year 12) and just general laziness. I also am not very good at doing buildings, so I may need some help (not that I want to offload it to someone else just because I'm lazy - that's selfish XD)
I will try and do more work on it in the coming weeks, but I can't promise anything.
