TaosWoman-Just think of all the pie points you will have earned! I haven't ridden any full centuries (on next years list of things to do) I have, however, done a number of organized rides. For the most part I have found them to be enjoyable-well stocked with food and with friendly people. Some people do not like the group rides but for me it's a social thing as well as a good way to ride new roads. Pick your mileage and ride on.
