Scott..maybe I was reading too much in the OPs opening (and only) posting. He indicated he was concerned with, quote "Any steep climbs or descents there? close quote. That indicated, to me anyway, some inexperience or concerns with both and 550 meets those standards in spades...you are correct though, we should probably limit advice to the question posed.
To the OP.. "Any steep climbs or descents there?" Answer: Steep Climbs: Yes, 25 miles mostly straight UP, with many switch backs and speeding cars. Descents: Very steep descent if you mess up on one of the switch backs because there are no guard rails......Dennis
