One of three things: random guys, the Chupacabra, or, and don't laugh, extraterrestials.
I'm much more inclined to believe this is the act from some guy, not so much the Chupacabra.
However, until a few months ago I would had never considered the extraterrestial option, but I really don't know what to think of this after having witnessed a weird event with a few cousins. Lets just say that there is some weird thing flying around the La Vega sky and its not noisy, but it is bright and orange. Initially thought it could had been Chinese lanterns, but I'm not fully convinced. Plus it was night time, cloudy and drizzling, so they had to be very low. These lights appeared one after the other and in a straight line, with no noise and as constant slow speed. The originated in the cordillera Central and disappeared in the direction of the Santo Cerro. Certainly someone driving along the autopista Duarte must had seen them too.
Nothing makes you think the impossible until seeing weird things with your own eyes and having others see it too. This last part helps in not thinking you're losing your mind. lol
