I bought a standing bike rack for 4 bikes - similar to the 4 bike rack on SK's link and I've devoted pretty much a whole room just to the bikes. It's hilarious coz the cats use the bikes to hide under so the dogs can't chase em - take about dual purpose! If I get a 5th bike, I'm not really sure what I'll do - get another house maybe? lol
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
