Hi Jim,

It takes lots of "FREE SPACE"!!  Far away from sensitive electronics, 
neighbors, and law.  I think an all metal big shed type building out in the 
back 40 would be great!!

I ran into the computers and "home" were "too close" as a big 
restriction... :-p

"Store" most of the "toys" safely away at home since they are easy to carry 
out as needed to the range...  If it is all metal and concrete with a good 
power shut off, fire is a tiny worry (unlike in the basement of your (my)) 
house...

You can "build" the stuff "anywhere", but you sort of need a "missile 
range" to "use it" ;-))

Just a concrete slab, underground 120-0-120 cable, and an all metal shed 
from the local place would put you pretty much "state or the art" as far as 
infrastructure goes...  If you don't have "that", everything else becomes 
very "limited"...  BTW, a cheep gas generator these days might be cheaper 
than any electrical cable work...

If anything goes "bad", you "just run" since the damage will be minimal in 
any case as long as you get out alive...

Not that local farmers may have your prefect "lab" available to you for far 
less money for "rent" as needed...  In many cases, the floor may be dirt 
then, but who cares...

Cheers,

         Terry
