When I was a kid I loved the Cal Academy. I loved the stuffed animals (at the time I didn't know they were real... I just thought they were like the Disney ones) and could spend days roaming the halls. Well they closed it on my to remodel... which is cool but I am not as happy with the new one. Ok I still want to move in and live there but still.
The new Rainforest part is amazing and fun to go through. I am glad the folks made us wait in line for it but the only part with stuffed animals anymore is the Africa part and that is tiny. The other exhibits seem lacking to me and the living roof is cool but doesn't have many details of how it works or what is growing there. It just feels big and empty in parts... but I could so fix that if they needed! But I doubt they will ever come to me to fix it.
However, our advice is not to go when school is on break. J and I had no problems but everyone else was in line for days. It just can't handle the number of people who want to use it, which is sad. It is a cool place and I did get a membership so I will be going back but it is smaller and not as cool as I remember it. Oh well.... I guess I will have to get used to it. Still better than almost any other natural history museum I have been too (the one in North Carolina was cool through).
