I know what you mean.
I live in Maynard, Massachusetts, and had a simlar experience. My wife sometimes thinks I am a whacko. I live in the flight path of Hanscom AFB, used to be a USN jet mechanic, and a certifiable aviation nut.
I am constantly running out of the house and looking in the sky, while she shakes her head. Of course, anyone who has worked for a while on planes knows that they ALL have a distinctive sound, and with a discriminating ear, you can tell them apart.
One day, I hear this sound...and I say to myself...those are radial engines...multiple engines. The list is fairly short....so I run outside and....
A B-17 is flying directly towards my house at about 250 feet!!! I couldn't effing believe it!!!! So I'm in my backyard, jumping up and down with my arms in the air going "WOOOOOOOOOOOOOHOOOOOOOOOOOOOO!!!" at the top of my lungs...:)
I also saw a B-25 one day...but it is frustrating to try to follow that through the trees, but there was no mistake about it. It apparently landed at a small community airport with some kind of landing gear problem.
I am sure my neighbors bring their kids in when I am out now...
Shortly after 9-11 I was out BBQing on the back patio and two fully strapped F-16's passed right overhead headed west toward the bay. That gave me warm fuzzies.
