Me and a few buddies got pretty deep into this stuff for a while in the mid to late 90's. So much that we would load my old 486 laptop in the car, take a 50' long phone extension cable and drive out to a COCOT in a rural area in the wee hours of the morning, and "beige box" off of the COCOT, sitting in the car 50' or so away. Our thinking was that a passing (police) car wouldn't notice the wire laying on the ground and that we'd be just a random car parked in the parking lot... probably kids making out, or somebody reading a map or something. Anyway, we'd sit there half the night scanning for dialups, then drive to a nearby telco exchange with a dumpster conveniently located outside and trash for passwords / modem numbers, etc.
For a while we had full control of a DMS-100 switch owned by the local telco. Unfortunately we made the mistake of calling it from my home one day, and as soon as we hung up the phone rang, and it was somebody from the phone company! That was the beginning of the end of my phreaking "career".
However, if you were to go to my parent's place and root around enough in the old storage shed, I would not be surprised if you found a box or two of old telco printouts and manuals, and maybe an old grey plastic Craftsman toolbox full of phone handsets, stolen telco tools, a 7/16" nutdriver (it opened a lot of the equipment cans our local telco used, as well as the demarc boxes on the sides of buildings and houses), and a bunch of RJ11 and RJ14 extension cables, RJ11 splitters, wire cutters, alligator clips, etc. Come to think of it, I should probably get rid of that shit in case the statute of limitations hasn't expired. :-)
That's some serious street, err hacker, cred. :)

Edit: Looks like the ban was not permanent.
Oh, and for a while there was soundblaster support that said, "Yo we found a carrier" whenever it hit a modem. Good times.
I'm the marketing guy at 2600hz, and we're setting up some really cool things later in this year to pay tribute to the counterculture. I'd love to talk more.
