The 35th annual of the grandaddy of amusement part haunted attractions, Knott’s Halloween Haunt lists 27 “Terrifying Nights” this year:

Sept. 27-30, Oct. 3-7, 10-14, 17-21, 24-31

Usually, by this time of year little tidbits about new mazes and shows that are being built are appearing on Ultimate Haunt by now, but for some reason this year the fan site’s message board isn’t running, although other elements of the site are being updated with new interviews with event staff, and has other “official” info.
