It's warming up outside, so who needs pants?

Cupid's Undie Run happens in downtown Boise Saturday starting at noon, and yes it's as much fun as it sounds.

Runners will meet at noon at Tom Grainey's, party, do a quick run at 2pm in their underpants, and then party some more. It's not like we needed a reason, but there's a great one.

The run benefits the Children's Tumor Foundation, and you can sign up right now for only $35.

Feeling a little shy? Don't worry, you don't have to run in your underpants. It's just highly encouraged.
