I just read this really cool article concerning Ohio state University and the weather there. Here is a very interesting paragraph:

"I once knew someone who carried snow emergency equipment in his car 12 months a
year, "just in case". While this is a bit extreme, weather here is much as the
saying goes, "if you don't like the weather in Ohio, just wait an hour." If
you're going to spend a year or two or four here you will need everything from
heavy winter gloves and boots to light tropical summer wear...and everything in
between. If you have to switch from "heat" to "A/C" on the same day...you're in
Ohio. "
