My son and I have been tossing the idea around as well, but we are far from ready to do it, I do have lots of ideas if anyone is intrested, and willing to share them openly.
alot of the upkeep and setup is relatively simple actually at least in my opinion.
Simple structures built, one main issue to keep in mind perhaps is to make it so that there is a way to get in and out of the building with large equipment of some sort. IE a fork life, this way you can constantly change the Scenary this way it doesnt become bored and mundane.
Just my two cents worth.
