Rode in today but it turned out to be a bad choice. While the streets were fine the MV Trail was a mess, particularly between the airport and the 14th Street Bridge. The bridges were a mess, with rutted, glazed ice and the paved portions were completely un-treated and un-plowed and similarly tough. I tried to ride in the grass once I got to the rugby fields, however, that proved nearly impossible-a lot of wheel spin and sliding. So, I mostly walked from the airport to midway across the 14th. Street Bridge where the pedestrian lane became rideable. It was smooth sailing from there on. I have to assume the Park Service won't treat or plow and have to make a determination whether or not to ride home today. They're calling for a high of 42 and partly sunny, not sure if that will be enough to melt the remaining ice. In addition, the run off from the rugby fields will be substantial, it will drain right onto the trail, probably preventing any improvement of the trail surface. I have to figure out what my "go, no go" temperature would be in order to make it home in a reasonable amount of time, it would probably have to be in the upper 40's to near 50. I'm leaning toward taking the Metro home today.
