"Don't get too used to the facilities here. Once you leave SAIL it's stone knives and bearskins as far as the eye can see." "Stone knives and bearskins" was a colorful phrase Mr. Spock used in the Star Trek episode-"The City on the Edge of Forever." He was referring to the 1930's technology he was forced to use to repair his tricorder. I've been under the weather, home sick from work the past few days, staring blankly at the tv...this phrase triggered this little knife of stone and wood and sinew.
