I rode the CRT again today and tried to obey the speed limit. I think I averaged about 12mph. It's tough to go that slow consistantly on a such a flat stretch. Interestingly there was a cop at the end of the trail. I happened to be doing a blinding 8 mph when I passed him.
Earlier in the day I was on the SRT and saw a guy fly past me and nearly cream a little girl of about nine of ten years old who was a little ways ahead of me. I was doing about 16mph at the time. I think he was doing better than 20mph.
