The organization SmartTrips is holding a competition for anyone who works downtown. Email or comment in their blog with your reasons for walking, biking, busing, MAXing or carpooling (anything but driving a car alone) and you could win certificates to Hot Lips, Bike Gallery, and more.
SmartTrips also offers a commuter packet for anyone who works downtown, delivered free to your work with a gift. You can request maps, bus schedules, bike maps, and specially tailored information such as women on bikes. We ordered one and were really impressed with the information. It gathered all the materials we've meant to pick up over the years in one envelope, and came with a bar of chocolate.
