It's funny, I would consider my bike my obtainable dream bike but I still lust for more bikes. We have a decent size house (1,700 sq ft) with a two car garage but we're still overflowing with bikes. The two 29er mountain bikes live in the hallway to a room we seldom use, two road bikes in the seldom used guest room, DH's 26er FS is in the garage and DH's Cyclocross bike is also in there. I guess the good thing for us is we are childless so our spare rooms are just wasted space. We want to downsize one day, so bike storage will get interesting I guess.
