Chunks officially end at dusk.
A. Good idea. The event is held in a large field. Most spectators stand by the fence, but later in the day a place to rest is always welcomed I am sure. The viewing area stretches for a long distance and there is plenty of room to get a good view. You will see people with platforms on buses, vans, and other inventive viewing venues.
