Yes, it's the same river.
We have a bike path that parallels the river that serves as my bike commute route. It makes bike commuting really easy when I hardly have to ride on roads for almost 20 miles.
I spent many a weekend on that river. Freshman year in high school me and my best friend went canoeing every weekend starting the second weekend in January, we had to pull the canoe across the ice the first two weekends, we were a little crazy I guess you'd say, the excesses of youth!
Well, good to hear that we have a little in common, It is a small world isn't it!
Did you say you did a 20 mile bike commute? If so, I take my hat off to you, that must make you feel great! I'm impressed.
