I like group rides. The fitness center where I work out has a weekly group ride. I ride that when my work schedule allows(which is almost never because they ride in the evening while I'm at work). I like the big event rides like the MS-150 and The Great Ohio Bicycle Adventure. Now that's a big group. That said most of my riding is solo. I live in the middle of nowhere, I ride to work. I'm the only one where I work that rides a bike. I just got back from a week in Williamsburg Va. I rode my bike alone. I used to haul my wife's and my sister in law's bike down to Virginia every time we would go visit her little sister. A lot of hauling and not much riding. This year I just brought my own. My wife likes me to ride with someone in case something happens. Can't find anyone wanting to do the rides I do at the times I have to do them. She about had a fit when I did the Washington to Pittsburgh trail by myself. I have had a few crashes over the years and yes ambulances were involved along with months long recoveries so I can see why my wife worries. In fact right now I'm still off work recovering from an accident where I was ambushed coming home from work at 11:30 at night. Three deer jumped me as I was going 25 mph down a hill, deer are evil. Now she thinks I shouldn't ride my bike to work.
