The railroad park has both full train cars and model trains. There is even a miniature train that you can ride around the park. I think this will be another excellent chance to capture motion with the model trains. The park is open from 11 am to 3 pm, but I will be unable to make it before 1:30 pm, your welcome to meet before then.
Remember to bring a tripod, to capture slow shots and empathize the motion.
