If some folks are bold enough to drop their pants for the annual No Pants Light Rail Ride, they shouldn’t flinch at stripping down to their intimates for this run that benefits the Children’s Tumor Foundation. Thirty-eight cities are participating in this year’s undie run, which encourages participants to wear their “bedroom best.” (no nudies!). Oh, and for those worried about too much jiggling: the run is only around a mile long. (Anita Overcash)
