For the Tybee Island folks, I've calculated the time from Douglasville to Dublin as being about 3 hours. If those folks stop in McDonough, Exit 218 there's a QT just to the left. If you refuel there it should get you to Dublin where we will all refuel.
For those out in the East side, I've calculated the time from Lawrenceville to Dublin, going cross-country as being about 3 hours, also. If we fill up in Lawrenceville, we can make Dublin on one tank, or for safety, refuel in Madison.
Everyone can refuel in Dublin and make the 2 hour trip to Tybee Island on that tank.
With that travel time in mind, what time shall we meet in Dublin?
