On October 16, Ann Arbor Parks is sponsoring Trick or Treat Down the River from noon-4p. You'll begin at Gallup Park Canoe Livery. As you paddle down the river you will run into creatures handing out treats and candy. You are welcome to dress up in costume. Please bring a bag to hold your candy. Keep an eye out for the pirates patrolling the waters.
The event costs $22/boat. No pre-registration is required. All ages are welcome.
