Re-do Boys' Bedroom

I am on a mission to re-do the boys' bedroom this summer. They are out of the little boy stage and being the old age of 8, I think they need a more mature theme to carry them on until 13! I can't stand the thought of them becoming teenagers, but that's another post. Here are my top four selections. Please tell me what you think. Both boys are "ALL" boys - they love dirt, cars, bugs, frogs, dirt (did I mention dirt?!)


BEDDING:

I really like the colors in this one. And, I like the transportation theme. My boys love airplanes, cars, and trains.

I like the heavy machinery theme and I think this is very cute. The only concern I have is all the white on the quilt. Did I mention that my boys LOVE dirt?

I really like this one too. I love the black gingham trim. I think read and black would be pretty to accessorize this room. I don't know if it's "manly" enough for the 8 year olds.

They love bugs and spend most of the summer capturing bees - I know, I know. But, what are you going to do. They feel so proud when they capture a bumblebee. They always let them go after I tell me to do so. I just don't know if this is too girly. I love the colors.

So, what do you think?
