Starfish - yep, me too; I've had the litter hotline on my speed dial for a while now...and use it too. It catches my eye when I spot something being tossed from a car window and, you know what? it's always been a cigarette butt! I react as a rider, in that it is not only littering to me, but a fire hazard too! What if that still burning tobacco hit my skin while I'm riding near that car? Arrrghh, I'll be damned if I agree to some idiot's careless branding on my arm, face, etc! And, how about anyone driving in a convertible getting hit?
It's just amazing that people still smoke, then carelessly toss their burning butts out car windows without a thought as to who else they could be hurting or maybe even causing a wild fire if it hits dry brush during our summer season.
If the letter that is sent helps get one person to pause and think before doing that again, then it's worth it and yeah, it helps calm me down too!
