Leslie Sturges, 50, spends her summer nights feeding and caring for bats inside her Northern Virginia home. Do you have a story to share?

Most recently, I spent time with a group of medical students who check the health of families who are checking into homeless shelters at night. I also hung out with some guerilla entrepreneurs before Valentine’s Day to learn about the science of street vending.

But I need your help. I will be traveling all over the region, from Baltimore to Richmond, in search of people and places that come alive when most of us are falling asleep. Who should be featured next? Where should be my next stop?

You can tweet me at @newsbysamuels or fill out the trusty form below. I read every entry and tweet. Don’t be afraid to nominate yourself or a friend.
