The Ride to Work thread made me wonder - what vehicles do you have at home?
I just have my bike, so I ride it pretty much every time I go somewhere. My wife has a car though, so I can use this if I need to and she doesn't need it.
Much as it would be nice, I reckon life would be inconvenient without access to 4 wheels.
I plan on adding another bike to the garage at some point, maybe in 18 months or so.
