How much is time worth to you?

There are a lot of grandparents that read this blog (most of my readers are my kid's grandparents :) )

How much do you think it's worth to spend a day with your grandkid?

If you had to pay $100 (in gas, or lost wages, or whatever) would you do it?

What about $200?

$300?

Personally, I would pay nearly any price in gas or lost wages to get to see my kid more. Obviously not all parents and grandparents feel this way, though. How much is time with your family worth to you?
