The festivity-minded folks in Key West, Florida, have a pretty cool Halloween-time tradition - a Zombie Bike Ride. (All zombies can lurch about, but I'm guessing only the more graceful and balanced zombies can propel a bike forward.)
All of these people dressed for the occasion! Except for the smart-phone zombie girl in the foreground. Or at least I know I see smart-phone zombies lurching about every day... mostly on foot but sometimes on a bike.
