Here's one for the brave, or at least those who like to take off their clothes for a good cause.
Cupid's Undie Run makes a Detroit stop to raise funds to research neurofibromatosis, a genetic neurological disorder that causes tumors to grow on nerves throughout the body and affects 1 in every 3,000 births. The event kicks off at Detroit's Tin Roof with some drinking to help get people in the mood, then commences for a mile run that ends back at the Tin Roof for a nearly-naked dance party.
If that all sounds like too much work, at least the people-watching should be good.
From noon-4 p.m. on Saturday, Feb. 12; starting at the Tin Roof; 47 E. Adams Ave., Detroit; my.cupids.org. Tickets are $50.
