Thanks to everyone for their concern.
It turns out the doctors don't think my Grandpa McCampbell had a stroke. They think it's more along the lines of some sort of amnesia.
This is good!
But just to prove what kind of a guy my Grandpa is, before they got all the test results on whether or not it was a stroke, my Grandpa was out mowing the lawn. Yes, mowing the lawn!
What a guy!
So now he'll have to go and see a neurologist to try and determine what else might have happened.
I'm going to Missoula on Saturday evening or Sunday morning to help out in anyway I can.
