Oh, ya, tell your wife next time remember to take the keys out of the pocket before she buries someone in the back yard, it makes it hard to get in afterwards if you don't. Oh and SPELLCHECK, it's your friend....unlike most here :D
I am a Paladin, like the warriors of old, ready to stand on the line to keep others safe... A Sheep Dog, ready to protect the herd from advancing wolves!
