Charlie had to work today so I was on my own with the boys. We rode the MARTA train to downtown Atlanta and spent the afternoon playing at the Centennial Olympic Park. After Charlie finished at the convention hall he met up with us and we rode back to our hotel together. Isaac loved watching out the window and thought it was so cool that the train went both above and under ground. Luke was most excited about watching the train as it came into the station. Once we were on, he wanted to get off at every stop.
