The reaction is San Juan should be carefully watched by regulators in New York City who have yet to fulfill their promise of banning similar horse-drawn carriage in Central Park.
De Blasio's silence is confirmation that he took up the contested issue as political tenet for the campaign. It's also a win for the city's tourism industry, of which the carriages are a large and visual part.
Passengers playing fast and loose with the rules in order to stay close to their pets and save a little money, too, further degrade the already degraded flying experience.
It will be difficult to quell demand for the popular elephant rides so activists' time would be better spent pushing for regulations that make it difficult for operators to run a business built on animal cruelty.
Interestingly, opponents of NYC Mayor Bill de Blasio's proposed horse-drawn carriage ban point out that the horses get a guaranteed five-week vacation on a farm every year. Americans would sign up for that on the spot.

Tourism is a powerful economic tool that can be used to boost an area's economy, further conservationist movements and protect cultures. This is a great example of the industry's power when it comes to animal and environmental causes.
The decision to again allow horse-drawn carriage rides in Vegas comes right as New York City's new mayor considers banning them, stirring up hot button topics for tourism and animal rights organizations in both cities.
