In this county they long ago seeded the roadsides with wildflowers, mostly native to our state, & it looks so lovely & puts a smile on my face too. I giggle with delight as we drive along. We have also noticed that when the wildflowers are blooming, there is no littering. People just can't bring themselves to throw litter out the windows of their cars & ruin the prettiness of the roadside. It's a win, win situation!
