As a kid, radio shack was my “Candy shop”. Heck even before there was Microsoft, there was Tandy with their file based OS. I learned my trade on the TRS80s, and my first production software product went live when I was in 11th grade for those computers. Oh the memories...
I remember when I bought one of their little rectangular FM transmitters and had so much fun talking through my neighbor's radio once I found the station they were on. Not too much of a range, but still fun when sitting around the corner and talking over their speakers, lol. Now the only place I can get electronics parts, etc is 2 hours away at Frys.
I used to know where every Radio Shack in all the areas I frequented was. (ya know, before gps and google maps.)
Once I was driving home from Georgian Bay Ontario in my 1985 Saab 900 just crossing the border from Ontario into upstate New York, and my car started to really overheat. I pulled over there on Route 81, and found that the electric fan for the radiator was not being told to turn on by what must be a dead temp sensor. (this was the first car I'd owned with out a mechanical, always on attached to the belt drive radiator fan.)
Bad sensor. 8 more hours to get home,. early 20's, not exactly carrying a lot of cash for out of state road service, etc...
Then i recalled driving by that Radio Shack just a few miles down off the highway in downtown Watertown. Thank god I preferred the Rural RT12 as soon as I could get off 81,. otherwise I'd also have missed one of my all time favorite diners, Loyde's of Loweville. 
So that hot August day in the parking lot of a Radio Shack in upstate Watertown NY, I took some speaker wire, a nice matching black rocker switch, and wire nuts and re-ran the fan wire bypassing the dead sensor and in it's place had the rocker switch in the panel to the left of the steering wheel. Now my radiator fan was a manual rocker switch. By the time I got home, i was so used to watching the temp gauge and flipping the switch manually, I never bothered to replace it. I just kept doing it manually for another 3 or four years.
