Question answered: they're awake
The dogs woke me up at 6am by barking this morning. They were both standing under the curtains in the bedroom, looking out, barking their fool heads off. Considering that I got off work at 11pm I was none too pleased. But when I looked out the door I couldn't yell at them. There was a big black bear grazing on the manzanita about 50 feet from the house.
We'd been wondering when they were going to wake up. I guess that question's been answered. I also guess I won't be taking the dogs on the trails behind the house this morning. Or for a few mornings...
