The tape is the kind that you seal cracks and openings with. So bugs and pollen don’t get in. I can’t believe there’s anyone that can simply place an AC unit into a window close the window on top of it and call that installed. There has to be gaps and openings that are either taped or stuffed with that foam which I also use .
As far as the bear goes.. I’ve read they’ll only go after you if they have cubs with them which there was not that I saw. But when it stopped and reversed direction towards me, the fear factor went thru the roof. I was not about to find out. I’ve heard you’re supposed to zig zag when running from them. There were a few houses thru the woods I was considering running towards . I’ve seen all kinds of wildlife during my early AM runs over years.. wolves, coyotes..woodchucks, opposing. had a deer literally bolt across road inches from me.. but my biggest fear came true today.
