I had to share this quote for you as when I read it, I laughed so hard I may have had a bit of projectile snot land on my computer keyboard.
"Dogs feel very strongly that they should always go with you in the car, in case the need should arise for them to bark violently at nothing right in your ear."
~ Dave Barry
And now I must go clean my computer.
and yes, i realize you might not think it's nearly as funny as me. but I'm OK with that.
