This is not a knock to anyone but rather a learning lesson. Some of you had said good job for keeping it upright and good thing you didn't go down, but let me be the first to say next time you notice something like whats quoted below DON'T GET ON YOUR BIKE AND RIDE IT. Hearing/feeling a grinding, scraping, knocking anything is not a good sign and you may as well just take a hammer to your bike instead of riding or do the smart thing and have the truck come pick the bike up first and determine where the noises are coming from before hand.
As Some of you may know (if you read my first thread) I was hearing/feeling a grinding, scraping noise from underneath my bike.
