2005
I did the 2005 ride. Overall it was very good for an organized ride. There were a lot of very good (fast) riders for an organized/charity ride. I'm sure there were guys that were at the stops before they were set up.
The last part of the century is a bit of a let down compared with the first 2/3, but that is more a factor of the quality of the early miles (which are scenic and some decent climbing). My main gripe would be that there is a 20 mile section in the middle of the route that is hard dirt. I could do without that - esp. last year as it rained the day before and made for extra mud and muck. Not that it is a deal breaker, but something to be aware of.
