Jubal, I think you didn't notice that it was ELECTRONIC components being asked about. As far as I know, there are no local sources for these things in Wyoming. Might be a very good business for some entrepreneurial Wyoming transplant to consider setting up. The manufacture of components and building communication devices of all kinds should be a winner once the hammer falls. But then, what do I know? 
Copper is mostly from El Chino mines in New Mexico, some avionics and electrical wiring types places exist in Kansas, Nebraska, and Missiouri. The bulk of actual microcircuits, solar panels, and all the rest are still based in California, Washington, Arizona, and Nevada.
If things fall apart however, there is the advantage of old infrastructure dumping. Self assembling circuitry is still pretty simple,
but if all peoples needs are less in the short time it could be giving a leg up pretty fast.
Consider the rise of continuous cast steel production in japan post WW2 vs US industries like Bethlehem steel that has infrastructure
dating well back into the 1800s. Hey if it ain't broke, don't fix it, who cares if it uses six times as much energy.
Anyway, that's probably way in the long term.
For someone new and renting there's bound to be a long checklist of things to check into first. Furnace filters, burner health,
critters living in crawlspaces, attics, if the coyotes get into your trash, coons in the garage, rusted shutoff valves, hornet
nests from previous years, which phone jacks work, which light switches go to what and "mystery" switches that seem to go
to nothing. Oh yes, and for computer geeks the best thing to check has to be the hot,neutral, and ground checker plug in
device.
Rentals in rural areas are amazingly bad for having hot neutral lines, this can lead to much excitement when networking computers
in different parts of the house.
The other one tend to be grounded plugs with no ground. Usually the "fix it" guy just replaces
the old two prong plug with a three prong plug when the old one breaks, on a good day he can remember that the black wire
goes to the small hole side. On a bad day this person might get confused and be thinking DC wiring, black is ground, just add another
wire from the black side to the extra negative plug on the bottom.
Let see, hornets in the AC unit outside(for central heating/cooling) are good to know about before you turn it on. If there happens
to be any simple burried cable powering the garage before you dig around to perimeter of your house. If the garbage disposal really
works or is just there for decoration/irritation and the same for any dishwashers. Washers and dryers are about the same situation.
Tubs and toilets also tend to provide some excitement after the first week, as specially if the house was vacant for a long time.
So just normal day to day living is bound to provide endless excitement in the short term I'm sure. As specially if someone asks
a question like "why is this old stack of pallets covered in old junk and newspapers buzzing ?" The answer, bees love abandoned
old pallets, as specially ones covered up already. How many bees per pallet one might ask ? Lots, a whole lot!
Hmm, funky smells from stoves are another good one. Dead mice in the bottom drawer add a special something to those pot pies.
And then there are carpet stains that don't show until you have all your lighting put in, and a pile of furniture already set up.
The best one has the be the old "haunted house effect". Load a house with furniture for twenty years, have it vacant for a few
years, and then reload it in a different patten. Add heating, cold, and moisture variability and the squeaks, creeks, and other
noises can be amazing.
If you have a room with a particularly annoying "ghost" try loading the center down with boxes of books, or dial the heat down to 60
before you go to bed, with any luck you won't have dual bias squeaks.
