First thing we did was headed to the monorail station in Downtown Disney. We told the engineer that Jonathan was learning about Trains. She let us ride in the engine and spent the trip explaining about how a monorail system works. Jonathan learned a lot there. Then the engineer told us that if we visited the main street train station they would let him ride in a train engine so that was our next learning adventure. It took a long time because we had to wait for the specific engine that had a place for extra people to ride in it. Don't worry, we spent our waiting time exploring the train station itself. Jason, Matthew and Jonathan rode in the train's engine with the engineers. The engineers told them all about how steam trains work, how they blow off steam, etc. Wow! So much learning packed into a brief time.
After learning all about monorails and steam trains we spent the rest of the day visiting Disneyland. Yay!
