A person could, should the person be so inclined, take the standard nose height of a North American Ground Squirrel as a guage in measuring the length of a rain drop trail, work backwards to distance travelled using the speed of said raindrop under normal earth gravity and thereby compute the shutter speed of the image.

Average speed of raindrops = 10mph.
Guessed length of raindop trail = 1 inch.
10 mph = 180 inches per second.
Shutter speed = 1/180 second.

This one was shooting for bold not old, spending most of the morning in and on the bird feeder despite the world.
I took this shot from just inside the kitchen window, about ten feet away, and also got a bunch of photos standing right next to it.

Here in the north east they are called Chipmunks. Now there is a striped ground squirrel from Nebraska (and other squirrels I know come from Nebraska...), but here it's a Chipmunk.
In Nebraska there is a striped ground squirrel, but it has 13 stripes or lines.
The following is from the NebGuide from the U of Lincoln, Nebraska.
Thirteen-lined ground squirrels are members of the squirrel family which includes chipmunks, ground squirrels, tree squirrels, prairie dogs, and woodchucks. Three other species of ground squirrels live in Nebraska, but are relatively uncommon.

Excellent!
1/200 second according to the EXIF data.
Do I win a prize? ;-)
Sure, sure. It said anonymous, not hieronymus.
How about a free squirrel picture?
This site clocks a raindrop at 11mph or 200 inches per second.

Cute little bugger!
That's a nice arrangement. How did you get the critter to agree? Bribed with nuts?
How's that saying go:
