What is the best way to get there on Saturday, February 24, 2018, for the matinee of Memphis, since the Houston Rodeo Parade will be downtown and a lot of roads will be blocked off??

Take Dallas exit off I-45 to Bagby maybe.

You migjt call Hobby center and ask them. Might depend on time of performance . When parade is over and the breakfast for Rodeo Officers at City HALL

Parade should be gone by the time you want to arrive.
