If you complete your layout in a year, you're probably moving faster than the majority of folks out there. Guys who like running trains will have track down, minimal scenery, and that's pretty much it. I remember seeing a plywood pacific layout in one of the MR Planning magazines years ago; the owner said they put down the benchwork, started running trains, and probably wouldn't stop to lay down scenery.
The other end is the George Sellios types who will spend 15yrs detailing every little scenic bit, and those layouts take forever to finish. Everybody else falls inbetween, I guess.
For me, this hobby is for long-term enjoyment, and something to do post-retirement (which is a ways away, but retirement doesn't mean the same level of current income!). So, let's get the learning curve done while I can still afford it.
