Cecil, do you make your in-laws walk the plank.
No my mother-in-law in on to me. She refuses to walk out on the pier even when the pond is full of water.

I'm thinking not having any planks on the highway side may be a good idea.
The truth be known my mother-in-law is a sweetheart. She's my second mother and we can talk about things for hours. She just doesn't have the greatest sense of balance and the pier wobbles a little if you're not used to it.
