Look at it as a blessing, the more room for bikes you have the greater the need to fill it up. I have a 2 car garage, a basement workshop and 2 sheds where I can put bikes. My family bike count for the five of us is 11 bikes. Just maintaining those is getting to be a pain.
I know part of the problem is I am never happy to leave them as is. Something is always getting changed or modified. Which leads to more things getting changed. It really takes away from the riding time. But as long as I have the room, I don't see getting rid of any of them and will probably add more as the kids get older. My oldest now wants to start working on bikes and selling them too.
