Those aren’t raindrops on windshield they are from going through the puddles.
These photos are along the Mesabi Trail. It is a popular trail and it stretches a great distance.
Deep puddle which got deeper with every pass through. The red hue is caused by taconite.
Can you see garbage in background? Unfortunately people dump appliances, garbage and furniture in the old abandoned mines and within the forests. It makes me frustrated to see such a mess in the middle of natural beauty.
