Mr. Silver - I'm so glad you posted this! It's ironic...just today I was pondering grade percentages and wishing I could figure out how steep some of the hills are around here. I don't have GPS or anything else for measuring. I know what a 3% grade is like because the local bike path runs up an old 3% railroad grade. Now I also know what 25% looks like. Hmmm, does anyone else have pictures of a 5%, 8%, 10%, 12%, 15%, etc.? Just kidding

Good job making it up that hill...I would only attempt it in my super granny gear and even then, it looks like a challenge!
