We've also visited the Aquarium here in Corpus.  Caleb had so much fun!  He loves fish!!  There were some pretty big fish that he was really fascinated with.  He was able to touch some sting rays, star fish, and other that I have no idea what they are called, but it was exciting to see his face light up every time he saw a fish.

Some were scary and creepy too!

Caleb loved watching the dolphin show!

So far we have visited the USS Lexington.  Huge, HUGE ship ( I guess I haven't been in a ship this big).  Though I would not recommend going with a 2-yr-old.  People told us it would take us anywhere from 3 to 4 hrs to go through the whole tours they do- it only took us 2 to 3 hrs.  All my son wanted to do is run or touch every button or display while I ran behind him so he wouldn't destroy something valuable:)
