Although I do organized rides, the vast majority of my riding is unsupported. Part of the reason is that I've always felt that it's important to be able to take care of yourself. Another factor is that my wife is not a cycling nut and I felt it unfair to ask her to help out -- it's kind of like asking someone to attend a party they don't want to go to so they can serve as a designated driver.
Although there are many great rides you can do on your own, there are many where there simply is too much distance between opportunities to get water for it to be practical. Also, some of the more interesting organized rides/races require you to have a support vehicle.
Just out of the blue this week, my wife suggested that she might volunteer for such duty in the future. I got caught totally off guard by this since she's never expressed interest in helping me do things she considers insane in the past. This is huge for me because it means I might be able to do some rides I've wanted to do for years.
I was just wondering, how many people out there have someone they can tap for ride support? And why do they do it? I've always had great appreciation for volunteers at events, but I've never quite understood why someone who is not a rider would want to do it.
