Traveling to St Louis area in April. Need to rent a Sousa

[Joemac]

Traveling to St. Louis area April 15. Does anyone know if I can rent a sousaphone there? Or borrow one I suppose. I'm flying there for the weekend to do a 1 hour gig. Possibly a rehearsal in the morning. The thought of bringing my horn on the plane for an hour set is not a pleasant one. Also, if anyone has any tips about flying with a sousaphone please feel free to give advise. I do have a hard case for it.
