FYI from Jimmy Rigged, Night of the Living Tread Organizer:

night of the living tread is happening today night rain or shine, thunder or lightning. for the last three years we have had perfect weather, so, it was bound to happen eventually. if the weather is terrible i’m simply going to shorten the course. basically it’s going to be a big game of tag. everyone starts out as zombie killers, but, once tagged you must infect another mortal before continuing on to your checkpoints. there is also a moving checkpoint which will be roaming about a certain area. oh, and we just added a professional zombie killer who will be sniping zombies throughout the night. should be interesting.
