Dave, what you need now is a few "work-kampers." You could use some guests that have skills at doing something useful...like digging ditches, knowledge of basic plumbing, knowledge of advanced plumbing with a major in sanitation services. Those are common enough traits among busnuts...
I know how to pile it high and deep!
If taxes and the cost of fuel keeps going up, we'll all be looking for a semi-permanent place to 'squat!' Sorta like the mobile villages that grew during the depression.
Hope your surg goes well! You'll probably find that you can do more than your realize. Most post surg folk are far more active than the docs would'a thought. Now I ain't recommending you start running laps when you get home!
But don't be surprised if you 'convalesce' much quicker than expected...hope so!
