I don't know anything about the accuracy of a Garmin, but yes Virgina paved roads up to and over 25% do exist....
Seriously, the record holder is 30 some percent (there was a recent discussion of this on another thread) San Francisco, Pittsburgh, Seattle, New Zealand all have their share of steepies. I would say that hill is probably steeper than 9 or 10 percent easily, but I can't look at it and tell the difference between 18% and 25%. Remember now that we're talking about percent grade, not degree of angle (I would expect the Garmin to be pretty acurate though.. at least better than Topo - which I have used, but its too easy to come off the actual road and get variations)
