Not from that area myself (I'm over in Glastonbury, UK) so I can't speak to what you saw specifically, but I'm curious about something. When you say triangular lights, do you mean three separate lights arranged in a triangle formation that held position relative to each other, or was it more like a single solid craft with lights at each corner?
The reason I ask is that in a lot of abduction accounts I've been digging into, witnesses consistently describe the latter - one object, three lights, absolutely silent. But other sightings in the same regions turn out to be the former, which some people reckon is drone formations.
Did anyone in the thread manage to get video? And roughly what time Thursday night are we talking? Would be good to cross reference with any other reports from that night.
