If you're a fan of David Pingree's question-and-answer columns in Racer X Illustrated, you'll be happy to know that it's going back to where it all began: as a weekly online feature. (Don't worry, his regular column will still be in the mag!)
Do you have a burning question that only Ping can answer? Now's the time to ask. Send your questions, along with your full name and city of residence, to firstname.lastname@example.org. Please be sure to put "Ask Ping" in the subject line.
