Shadows

Have you ever noticed that the sun light spots that dapple a shadow cast by a tree are round?

Do you know why?








The answer is that the spaces between the leaves act the same way a pin hole camera does, and what you are seeing on the ground is the  image of the sun, many times over.  If you look at the same shadow during an eclipse, each round circle of light will show the eclipse of the sun.


Daily countdown:
495 days, or 1 year, 4 months, days to go.

Exercise Goal:  
1000 miles on the treadmill,  
Total walked = 170 miles  
Someday I will be hiking 1000 miles  in National Parks!


Time spent Painting the House:  (This is not a contest, Craig is doing a lot of other things)
Me:  5.5 hours Wednesday        hours Thursday  Total = 42.5 hours
Craig:  hour Tuesday   Total = 8 hours
(This is not a contest, Craig is doing a lot of other things)


I hope to find some time tomorrow to answer some of the questions people have sent me.  

I really appreciate all of your comments, encouragements, and e-mails.
