there are "adopt a highway" signs galore.
sometimes signs "highway for adoption"
when i drive for an hour or two, i need to stretch, so ifind a likely spot, pull over
and take grocery bag and pick up trash.
the trick is bend from the waist while doing this. i may only pick up 100 feet along the road, maybe 100 yards. then in my mind i donate that 100 feet for that day
to my sister who is a green freek, or any one else you want. i feel good for the stretching and the road looks better. we all could do just a little and people would see the campers along side of the road and not get so anoyed if sometimes we aretoo slow for them.
I like traveling, learning about our country.
