New Guitar Strings

I have an old acoustic guitar that has been gathering dust for the past few months in my room because the D string broke. Yesterday a friend came over for dinner and surprised me with a new set of strings. So now I've got a playable guitar and a new skill in re-stringing. It's been a while since I've practiced and many, many moons since I took lessons as a kid. One day I'll make an attempt at reading music again, and learn to play Classical Gas better than Mason Williams, but for now, I'm just going to try to play more often the stuff that I already know. Like Nirvana. Oh, how I miss the early 90's...
