Commuting to work via bike might be harder than I originally thought

Okay apparently you arent supposed to commute on major highway thoroughfares. So I'm guessing Cobb Parkway is out of the question. But the route they suggest me taking is crossing huge intersections and taking a lot of turns. Do they know how easily I get lost??! I have to take 25 turns and the way I was planning on going only had me turning like 5 times! Thats a kabillion more turns! 5 times more!! 500 % more turns!

The following website was extremely helpful though.

This was the site I went to to plan my trip.

ANd Im totally not giving up on commuting to work! I am planning on spending that rebate check on a 600 dollar bike. I think Im going to get the Fusion Novara REI brand.

Sweet? Sweet.
It has fenders and headlights and taillights. I think it has a nexus hub. And I have no clue what that means.

Oh, then I'll need a helmet, patch kits, tire levers?, tubes, wrench?, multitool? I mean, I wouldnt even know what to do with all that stuff?
How about just one tool?
A CELLPHONE.
