June 20th Two Bear

Now it's the day before spring really gets here. About 8:00 -8:30 PM,central New Hampshire. Darkening, but still light.
There are storm clouds about, breezes, a little rain & some thunder outside, but the real storm seems further north.
Then, just when the breeze drops off...crunch, crunch, snap & another crunch.....
We look by the forest's edge.....
Most go to the second floor, for a better view down the 'sloping hillside' to the forest's edge.....That's were they see 'them'.....YES 'them'...
First one big black bear, looking up the slope...right at us....then a SECOND big black bear follows behind, out from the forest into the thick ferns & bush...
Two big bears.....
Well, grab a camera? Or be sure the doors are shut and windows all down (and any lying around dinner remains secured)....well we can do both at once, right?
In minutes (100 seconds, maybe) we're back at the 2nd story windows, ready to film, feeling secure. But now no bears to be seen......where are they?
Certainly they heard us, and that means they took 'appropriate bear action....' but where are they??
We can see and hear over quite a distance (we think).....but nothing, not a sound, not a sight...
These were big animals....where are they!!!

We've missed the moment....or are they just waiting for the night to get darker???
