The bike I feel the most attached to has been in our family since 1999, when DH bought it as his first mountain bike. It's a bright yellow Voodoo Hoodoo hard tail. DH set it up for me to start riding on in the fall of 2000, even though it's a medium; I rode it on the road, with slicks for about two years, when I got my first road bike. So, from about September 2002 to 2006 it sat in our basement or bike shed, ridden once or twice by my oldest son to his summer job, and once or twice by a guest. When we moved to this house, I wanted an around town bike, so DH worked on it for me, I got a rack and pannier, new brakes, saddle, and the gears had to be upgraded. I used it for 2 years, going to farm stands, appointments, minor shopping, until we bought our Jamis Codas. In 2008, we gave it to our older son, who also let it sit for about a year. Then, in 2009, he took it out on the bike path by the Charles River and that was it. He was hooked. He started commuting and all around riding and used it all the time until last winter, when he got a single speed commuter and we also gave him his brother's classic steel Serotta road bike which had been hanging around since 2003. He still uses the Voodoo when riding with his wife, but right now he's in a little hiatus from riding. So, that bike is still going strong at age 11.
