5 1/2 for me:
Trek Portland as a commuter
Trek 2300 as a roda bike
Schwinn LeTour fixed gear
Schwinn Homegrown mountain bike/putz around with the kids/really bad weather commuter
Gary Fisher Paragon 29'r mountain bike
Cannondale Tandem (the front half)

Plus 4 1/2 for the wife and kids:
GF Kaitai
GF Marlin
GF Cosmo
GF Tassajara GS
Cannondale Tandem (the back half)

Plus 3 more operational small kids bikes that I need to clean up and sell.

No wonder my garage is so crowded...
