Some unknown security purpose

In the morning walk to the office. Work for a while. Walk home. Eat lunch. Walk back to the office. Work some more. Walk home. Ride my bike out to Mayfair Mall. Go in to buy some pants. Ride to 76th Street. The Hank Aaron trail is shut down at that point for some unknown security purpose. Another consequence of the Republican National Convention. Walk around West Allis. Walk back to my bike. Ride home.
