Wow, your garage looks great! I wish I had that much sq/ftage.
I'm taking Thursday and Friday off this week to work on mine. We moved into our current house almost three years ago, and I've never properly organized things. It's currently a disaster.
What interests me in your garage is that I also have way (way) too many bikes. I currently have five complete bikes and four frames. Between my wife and kids, we have six more. Add about 8 wheelsets and so many bike parts.. Uggh. I need to learn to part with things.
Is that a Salsa on the workstand (Spearfish)?
My garage is only a slightly oversized, a two-car model (that only has space for one car), and all of the walls are spoken for by things like doors, windows, a refrigerator, and a small built-in workbench alcove. There is no space for shelves or hanging anything. Half of the bikes are hung above my wife's car, and the rest take up floor space, along with a rolling shelf unit, and big recycling and trash bins.
Wish me luck, I need it.
