I have seen a few rides that start in Worcester, but mostly the rides are in rural/suburban areas, so the car factor isn't as bad. The group I rode with today, which is part of CRW is great, but even i won't drive to some of the places they start at; it's just too far for a day trip. However, sometimes you have to do this, so you can ride in different areas and vary your routine. And yes, YM groups tend to be "fast," in both the Boston and Worcester chapters. Maybe you could start a "slower" YM group of cyclists.
