The Tucson Parade of Lights is this Saturday starting at 6 p.m. The parade starts at 17th Street and 6th Avenue and ends at Armory Park. Don't make the same mistake I did and expect Bud Lights. Its actually the sparkly kind that run on electricity.
There's a downtown tree lighting ceremony beforehand at the new courtyard adjacent to Hotel Congress at 5:45 p.m.
Here's an illustration of the parade route:
