It is 8am on Sat, 9am on Sunday until later in the winter when Saturday will move to 9am. Sunday also changes in the winter to have the hammerfest at 9am still with a slightly more chill ride at 1pm if there's enough interest. Sunday rides are longer, in the 50-65mi range. Show up early. Sometimes they roll right on time. Usually people hang out for a cup of coffee afterwards.

When things change they'll send out an email to the local group: coastal_georgia_rides@googlegroups.com

Look them up on Google Groups. You need someone to add you to the list. PM me if you have troubles and I can send them your email to add to the group.
