Annie,
I have to agree. You can never have enough. I've got a road bike, a mountain bike, my old road bike I converted to a commuter, and a brand spankin' new commuter bike. I've also got a project/cruiser bike that was on its way to the dump and I couldn't resist. My husband's got a New Belgium Brewing fat tire cruiser, a commuter bike, a road bike, and a mountain bike. Is that too many bikes? We live in a condo and are required to park in our garage. Talk about some creative storage! (we've got two touring kayaks in there too)
