Time zone
Same local time
Origin and destination are on the same clock, so arrival timing is easier to judge at a glance.
Temperature spread
3 degrees warmer at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.

Spencer is in Western Iowa. A small town with a population of roughly 11,000. It is the county seat of Clay county. It is surrounded by a large area of agricultural land. The Little Sioux River runs through the town and divides it into North and South. Spencer is home to one of the largest county fairs in the world, the Clay County Fair. Being the largest community in the area attracts many people from smaller surrounding communities for both recreation and work.
Spencer was put on the map in the late 1980s, when the town library adopted an abandoned kitten and named him Dewey. Dewey became the unofficial town mascot over his 19-year lifespan. The head librarian's best-selling book, Dewey: The Small-Town Library Cat Who Touched the World offers an indelibly vivid portrait, not just of the beloved cat, but also of the town, and rural Iowa in general.
