The road that I live on actually switches from pavement to gravel about a quarter of a mile before I get to my driveway. That would make a lot of sense if that were the cause. I will investigate the pulleys tomorrow for rough spots when it's light out.
If those look fine it's more than likely from the gravel, which would be unavoidable I suppose.
Thanks for the prompt and helpful replies.
Also, the roads I ride between work and school throughout the day have been getting resurfaced, and when I try to take alternate routes I just hit more roads that are being resurfaced (I know, in Minnesota there's two seasons; Winter and Road Construction). I did notice that about two weeks ago there was a lot of loose chunks of road being flung up at me, and a larger one hit the bottom of my bike making a loud thud. I didn't notice much if any wear on the belt before school started back up and I was hitting the construction.
