Ooo... the other night when we were sitting in the living room, one of the dogs is older (my mom's dog), she's kind of a loner as the wifey doesn't much like her. Anyway, the dog comes into the room looking obviously unhappy, lays down in the doorway. Suddenly all THREE dogs randomly sat up (obviously very unhappy) and look out the windows. I'm kind of the go to guy about bumps in the night here, so I go outside to investigate.
There's a couple bats flying around, so it could have been the echo location that bothered the dogs. (Understandable) So I turn around to go back in when I hear this snorting from behind the garage. "Hmm, could be deer." I smile, one of the nice parts of living in the middle of no where is you get to see deer and wolves and bears up close. So I sit hoping to enjoy this experience with our neighbors, the deer. I hear hooves, like you'd expect. But then the BIIG tree that's out there starts to shake. Now I know from personal experience that tree is NOT easy to move around. It's an OLD pine and me (in all my heavy glory) can't even shake it...how is a tiny little deer gonna do it? Anyway, so I decide to start walking there to investigate.

I dunno why this seemed like a good idea at the time (kind of like using an explosion as a diversion... who RUNS TOWARDS AN EXPLOSION??) Once I get to the road, I hear wings flapping. Hmm, no biggie...sounds like bats or a goose. (Bats are more likely as it was past 10PM...birds don't much like to move after dark) But nope, surveying the sky I see no bats. I clearly scared the two away from before. Not to mention the wings were coming from ahead of me...like towards the garage.
The sound of these wings is what I can describe as either BIIIG wings or within 10 feet of my head. I didn't see anything...so hmm

Once I finally get to a place where I might be able to see what's back there (heavily treed area) the trees shake AGAIN, and the sound of hooves and wings go away from me...like away from the house.
That's it, I stood there for a minute but there was no more sounds...so I went back in and told the Wifey.
Now looking at this from a completely rational level, this could have been deer (I know bucks scratch the hair off their antlers using trees) which would explain the hoof sounds and the snorting. Now there ALREADY were two bats, perhaps there were some back in those trees as well. That would clear up ALL of that situation. However, there was an odd feeling to go with all of it so... I dunno. Maybe it's my imagination, it just doesn't feel like it to me.
Going off the deep end what could it be? Well we have experience with Native American "stuff" out here so...coming from that way I'd say Mothman. But that doesn't include hooves, unless that was tree branches snapping instead. Only other thing I can think of was Jersey Devil also known as Leeds Devil. Dunno about something like that making its way all the way out to Minnesota, but... yeah.
