After 5pm some of the parking areas are free, there's always the meter-managed spots in the loop at North Ave, and there's the free parallel spots along Centennial Olympic Park Drive (the road you turn into the North Ave loop from).
Also, I haven't gotten any of my CS homework done. Feel free to come over anyway though. I can just work on it while you're here. I'm not expecting it to take too long though, I'm just not going to bother with it tonight, as i have other stuff to attend to.
