Crochet Pattern - Oregon Trail

I know I previously stated that I would have this pattern up on the 1st, but since I plan to stitch this weekend (my test will be over with!), I will most likely have a progress update for Monday. So, I decided to go ahead and post this pattern a little early! 

One of my favorite games growing up was Oregon Trail. I loved it whenever we were able to play this in the computer lab at school.
Enjoy the pattern! 

I came up with this filet crochet pattern based on the old Oregon Trail wagon.

Here is the pattern itself:
