While I’m not crazy about them, I can cope with seeing a quaint carriage rolling along a dappled Central Park path or through a tiny town’s historical festival. But when I’m on a bus that’s buzzing by a horse-drawn carriage that’s clopping along in the summer heat, pulling blithe tourists pointing out the Hard Rock Café, my heart sinks.I don't mean to nag but horses and Hummers should not be sharing the roads. I cough up a black lung in the summer when I’m walking around an urban center for just an afternoon. I can only imagine what equine lungs inhale when Nelly is continually staring down the end of a exhaust pipe. Unless you plan on putting a surgical mask over her muzzle Michael Jackson style, she shouldn’t be pounding the pavement. I may not be a horse whisperer but I can hear her silent screams loud and clear.
