It’s a little after 4 p.m. Dancers have been on their feet for more than 21 hours. Block 7 just ended; three more to go. It was definitely the hardest block, many dancers admitted, the Louis Room of Norris lacked the contagion of energy it had just a few hours ago when dancers hit the halfway mark.

But Dov Shalman, a Weinberg junior and first-time dancer, said he’s surprisingly awake - mentally that is. “I thought I was going to get a lot more tired than I actually am,” he said. “It’s a lot more about my body getting tired rather than my mind.”

The vibe in Norris continued to fluctuate throughout the three-hour block. Looking around, there was a lot of side-to-side swaying, marking the dancers’ struggle to keep on their feet during the remaining blocks. After this block it will get better, one dancer said in passing.

But just when the energy was dipping into danger zone, Michael Jackson’s “ABC” came on and people began to bounce up and down, not holding back, like it was hour 29.
