Please tell the college students who run down [local road] to be more careful. They are running, sometimes 4 wide, into the lanes of traffic on very busy roads. It is very hard to see them in the shadows of the tree line on both sides. Yesterday, they were running all the way in my lane of traffic and with oncoming traffic, and there was nowhere to move. They are not wearing highly visible clothing, and you can't see them until you are right upon them. I'm sure in their mind, the rest of us will automatically just know they are there and to move out of their way, but with other vehicles included in the mix, along with weather conditions, they need to be more cautious.
