So let's talk destinations that would be open on a Thursday or a Tuesday (this knocks out Computer Recycling Center, as they're only open on Saturdays).
I know about:
Frys (yes, I don't get it, but people who don't have Frys idolize it for some reason)
HSC Electronic Supply (otherwise known as "Halted Specialties Company")
Weird Stuff Warehouse
Anybody else have tech/junk shops they can suggest?
There is, of course, also the option of a tour at the Computer History Museum too...
