Now that was a particularly egregious error but I do find that it regularly gives me readings of 18+% on a hill that I know to be 8% at its worst.

That said, it is a steep hill! The good thing about grades that steep is that it is difficult to make them *too* steep. (They never do seem so steep in the photos though, do they?)

Solobiker, I think I need to ride with you! I seem to run into steep grades anytime I head west!

Mr. is using the Garmin Edge 305. However he has not yet downloaded this info to the computer, and I do think that when that is done, that the software to do some sort of verification of accuracy.

I showed him this hill after hearing some of the guys at the LBS talking about it. Several very strong riders said they couldn't make it up. They all agreed that it had the highest grade in the area.

I won't even try it on my double. But it is my goal to do a lot more hill work and maybe take the triple Trek 1000 over and give it a try before the year is over.

We live on the Ohio River and this is something of a bluff here on the Indiana side. As Mr. said this hill is just 2 blocks off the historic towncenter. The Town of Newburgh was a bustling river town in the 1800's Can you imagine the horses pulling a cart over this?

The street that you see (where the first up picture is taken) is the main street through town and you cannot cross it without stopping. So there's not too much room for a flat start.
