Fixed heaven or hell?

I rode the fixie today to Jefferson Barricks and just chilled out. I kept the heart rate bewteen 135 and 150. My legs are pretty tired from the long ride yesterday. I am regretting riding the fixie because the ride is so stiff. I could feel every dip and bump in the road. Plus I am not set up very well on it. Tomorrow I am going to ride up and down Marshall for awhile. Should be fun.
