On Saturday we went to the Albuquerque Aquarium, and Noah loved it.  We were the first ones in, and we basically had the entire aquarium to ourselves for 30 minutes, how I do not know.  My only guess is that we didn't listen to the ticket seller and just went in.  They had a a ton of stingrays, which Noah seemed to like the most.  They had a giant coral tank, and a really big shark tank.  It was great for kids Noah's size.
