Oh my! I can just imagine how fast your heart was beating! I have had a similar thing happen, minus the barking dog. Our property backs up to a wooded area and behind that is a highway. Once a few years ago someone was racing down the highway with the police chasing them. Hubby had been downstairs late that night, or I guess I should say early that morning. It was around 2:00 a.m. He said he heard sirens on the highway and saw a man dash through our yard . We have a picket fence going across the back yard and a 6' wooden fence on all of the other sides. Apparently this person easily went over the picket fence and, since we had the gates locked on the privacy fence, he didn't take the time to open them and scaled the 6' fence, breaking the tips as he went. This all happened, as I say, at 2:00 a.m. and hubby had been asleep on the family room sofa with the screen door open to get the fresh air. I am glad I didn't find out about the whole thing until the next morning. Where were the dogs you may ask? Upstairs asleep me with!
