Here are few pics of what there is at OMSI. There is a big display of dinosaurs and tons of facts and information. The best part of the trip for me was the submarine. We got to tour the USS 510. It was a real submarine used a long time ago. The most interesting part was that there were about 90 men aboard this submarine for a week's time when they were on a mission. They could not take a shower and some of them smoked. There is absolutely no fresh air in the sub so can you imagine the dank air from BO and cigars???? I about died. The subs are a lot bigger now but this particular one was quite small and very tight. The sleeping bunks were very small. I was getting very claustrophobic just in the 15 minutes we were on there so I can't imagine being on there with no way out and the smell! I am glad I have never had to do anything like that.
