When the kids and I flew out to Colorado the boys were AMAZING! I was so happy. And as worried as I was about having a layover, it actually worked because just as they were getting antsy, it was time to get off and we had time to stretch our legs as we raced to catch the next plane. Then, when they were done again...we were in DENVER!! Just outside of Denver we hit turbulence, it rocked Sierra to sleep.....FINALLY!! And the boys said it felt like a roller coaster and had a BLAST!!
