Now that I have my own place, I decided to take advantage of it and put holes in the walls. :-) The first project involves getting a home theater audio system, wiring the speakers through the walls, and mounting my plasma tv on the wall. The results of the day (after some cleanup), are in the photo seen here.
To prepare, I got an entry level Yamaha system, speaker cable, and other bits and pieces from Best Buy along with a tv wall mount from Fry’s. JB was kind enough to offer to help out with the project so we got started around 1:30 on Saturday afternoon. It wasn’t long before we discovered that there were screws for the walls that were no longer in the box. I had seen another wall mount at Target that was a little cheaper (I know that you’re thinking, cheaper is all well and good until my plasma falls off the wall), so we took the wall mount back to Fry’s and got the other wall mount from Target. At Target, we saw a man wearing an umbrella hat (before you ask, yes, it was a grown man wearing a hat that looked just like the one in the link). After we got back and opened up the new wall mount, we found that it was missing some washers that we needed, so we just bought some replacements at a nearby TrueValue. 
At this point, we put up the plasma and started wiring the walls. It went fairly smoothly. Some of the high points included discovering that the wall we were cutting into had 2 half inch sheets of sheetrock on it, crawling around coughing on fiberglass insulation, JB fishing wires out of the walls with wire coat hangers, and finding out that my neighbor’s bedroom shares a wall with my living room when I got a knock on my door at 11pm. From this experience, I learned a few things: JB is a good person to have helping you fish wires through walls, picture hanging wire is pretty handy to have for a project like this, insulation in walls sucks sometimes, fiberglass poles are pretty nice for pushing wires through insulation, and a fiber optic viewer would really come in handy when you’ve got no idea where inside your wall that a wire is.
