[peoriapeoriawhereart]

I'm a little confused about the absence of weather except when it's there. (Note, this is due South) Three episodes between Good for the Soul set at Christmas and Call of the Wild, which is cold enough for ice fishing in Chicago.

Thoughts? Likewise, is there any intimation of what time of year Benton's mad pursuit of a serious 'litterer'?
