Part of Bossier City will be tied up for a parade tomorrow evening. Bossier City police will block several streets in the Shady Grove neighborhood near Elm Grove Middle School for the Parkway High School Homecoming Parade. That starts at Elm Grove at 6 o'clock, heads north on Van Deeman to Shady Grove Drive...then south on Parkway Drive to the parking lot of Preston Crownover Stadium, home of Parkway's football team. The parade will last until about 7:30.
