Come see the best men's and women's squash players in the world ply their trade in a giant glass cube as the J.P. Morgan Tournament of Champions returns to Grand Central Terminal for the 27th year. One of the oldest racquet sports in the world will take place in the all-glass portable Squash Engine Court, which doesn't have quite the same ring as "Hell in a Cell" but still sounds pretty cool. Best of all, free public viewing is available from the Vanderbilt Hall passageway.
