I observed these myself and didn't get them from any list.
- It's over 1000 miles to drive between Pelican State Beach and Quechan Casino -- both in California.
- The most northern point of Florida is still north of San Diego.
- Detroit is directly NORTH of Windsor, Canada.
- Cincinnati is less than a mile from the state of Kentucky.
- Spokane, Washington is just 90 miles from Montana.
- Milwaukee is just 90 miles from Chicago.
- The North Rim and South Rim of the Grand Canyon are 10 miles apart, but it requires a 212 mile drive to go from one to the other.
- The highest elevation in Florida is 345 feet.
- The lowest point in Colorado is 3,315 feet.
- There are four cities over 10,000 feet in the US (Alma, Montezuma, Leadville, Blue River), all in Colorado.
- A part of Oregon and a part of Texas are in the same time zone year round.
- Arizona leaves its daylight savings observance to the localities, so you never know what time it is when you're driving around the state during daylight savings.
