I will be travelling for a few days and will check your sites when I return. Here are the answers.
Here we have a soccer net, was it easy?
Abe guessed the Nylon rope right off and here it is on the soccer field. Abe has some of the best bird photos you will see on his site.

This is a chain link fence near the soccer field.
Rose was the first one to guess chain link fence and has a neat nature site.
Craig added plastic coated. Check out at the end to see this man's talent plus his site for photos.

The final one is a Burr Plant, I heard it helped in the development of Velcro. Check out the hooks and the way they connect to clothing as you walk by. Did you ever hear "Don't get a burr under your saddle". This is the reason, they do attach and hurt.
Warren got this one, check out his neat bird blog.

I do hope you had fun this week.
Craig and I shared some poems on
Joan's site after the guesses on Monday. She had a really neat salamander with the gills showing. Here are the poems, all in fun:
This was mine:
Here I sit guessing with a smile
unlike Craig who missed by a mile.
That will teach him ever to doubt
all my guesses,to him I will shout.
Craig oh Craig, you can try harder,
to guess like Tom would be smarter.
This is Craig's answer, it is a funny one.
Ode to Tom
Although it is true,
No one guesses like you.
I have missed them all,
By a continent or two.
The thing I can say,
And this is for certain
When Joan reads my guesses
Her sides start to hurtin’.
Deep in the wilds of Africa
In the wee hours of the mornin’
Laughter can be heard for miles
Without explanation or warnin’!
