We watched the dolphin show @ Shedd Adquarium -- it was just their 'practice/training' show, so it wasn't as dynamic as we've seen in the past, but it was still good.
Big sister LOVES maps -- here she is helping little brother read the map and figure out where we should go next.
It was a GREAT 2nd day of our stay-cation, everyone (except daddy) fell asleep on the way home and it was early bed for the kids and mommy is about to head that way too...
