Being year 6 or so of setting up partial walk-through display in backyard of Bay Area home of my parents - Western theme elements there year round due to a backyard railroad, so built up from there/expanded upon for Halloween.
At this point, basically, not much done yet besides some minor things, lighting being set up and a few figures - new elements purchased this year have to be integrated, and in the range of 8 - 10 full body figures or electronic characters with 'gags'/animation have to be set up plus small props, beginning Saturday at some point, meaning the bulk of the display goes up in just six days, whatever can get done. For the circumstances behind that happening this year, when most we'd have spread it out over doing a few things each day beginning mid-September, see this thread: http://www.halloweenforum.com/general-halloween/136336-2014-pre-halloween-slump-doldrums.html
This Friday will be last day of radiation treatment for the family member mentioned and they are determined invite over guests for Friday and Saturday night with display up and going - my enthusiasm still admittedly little low and concerned about their wellness level, but seemingly we're locked into doing it and opening the doors, so onwards it will go barring any major setbacks currently unseen....
Here is the current state of things, in essence.
