Fridays in May are bad because of the music competitons and school trips. It didn't help that monster was closed, Demon Drop was closed part of the time I was there and Hydra was also closed for a short time. Thunderhawk looked to be an hour because only 1 train was running and the last car was closed off. I rode Steel Force with a 25 minute wait and Zephyr which had no wait and left. I knew it was going to be crowded but I was in Allentown anyway today so I figured I would run over and take a chance. I left around 3 after staying an hour but by 5 or 6 once the school kids leave, crowds are usually better.
