I'm in St. Louis because of work, so I rented a bike at the Gateway arch and rode up the Mississippi river trail. Didn't eat before I left, and didn't realize that there are no businesses on or near that trail! Rode about 8 miles north, turned around and went back to the arch area to find some food. Ate the worst sub in history at the Gateway arch cafe, then headed south. That direction is on auto roads so it wasn't as nice and I didn't go as far.
But it was still a great way to spend a morning....lotsa bikes on that river trail heading north and a nice cool breeze blowing!
