2. Farmer’s Market: 13mi*20 = 260

3. Misc. rides to store:  52*10= 520

4. Critical Mass:  10*13= 130

Total Mileage:  5330

My Bikes:

1.  Circa 1997 Schwinn Homegrown converted to single speed with knobby street tires (work commuter)

2. 2005 Breezer Citizen 3-speed with trailer bike and child-car attachments (grocery getter)

Things I Bought for Biking (that I can remember)*:

2 pairs of shorts (baggies), Two poly shirts, 3 pairs of socks, 2 chains, 2 pairs of pedals, numerous tubes and patch kits, 1 pair cranks, 1 bottom bracket, one rigid fork (the suspension was warn out), 2 rear tires (my front tire is about 5 years old and has about 8000 miles), 1 saddle, 2 rear lights, 2 front lights, two boxes gauze pads, 2 boxes band aids, two rolls medical tape, 1 tube of triple antibiotic goo, 1 pump, 1 rear hub rebuild kit, 1 single speed conversion kit, 1 brake cable kit, 2 sets of brake pads, 1 set of brake levers, repair of internal hub (I messed it up trying to adjust it), one rear fender, reflective tape, 1 pair shoes (my others were 6 years old)

Keep in mind that this was not my first year of commuting.  Most of these purchases were required just to maintain the bikes.
